The following illustration shows two individuals communicating with each other.
Here, communication takes place through sound waves.
However, if two people want to communicate who are at longer distances, then we have to convert these sound waves into electromagnetic waves.
The device, which converts the required information signal into electromagnetic waves, is known as an Various types of patch and slot antenna />What is an Antenna?
An Antenna is a transducer, which converts electrical power into electromagnetic waves and vice versa.
An Antenna can be used either as a transmitting antenna or a receiving antenna.
Antenna can also be termed as an Aerial.
Plural of it is, antennae or antennas.
Now-adays, antennas have undergone many changes, in accordance with their size and shape.
There are many types of antennas depending upon their wide variety various types of patch and slot antenna applications.
Following pictures are examples of different types of Antennas.
In this chapter, you are going various types of patch and slot antenna learn the basic concepts of antenna, specifications and different types of antennas.
Need of Antenna In the field of communication systems, whenever the need for wireless communication arises, there occurs the necessity of an antenna.
Antenna has the capability of sending or receiving the electromagnetic waves for the sake of communication, where you cannot expect to lay down a wiring system.
The following please click for source explains this.
Scenario In order to contact a remote area, the wiring has to be laid down throughout the whole route along the valleys, the mountains, the tedious paths, the tunnels etc.
The evolution of wireless technology has made this whole process very simple.
Antenna is the key element various types of patch and slot antenna this wireless technology.
In the above image, the antennas help the communication to be established in the whole area, including the valleys and mountains.
This process would obviously be easier than laying a wiring system throughout the area.
Radiation Mechanism The sole functionality of an antenna is power radiation or reception.
Antenna whether it transmits or receives or does both can be connected to the circuitry at the station through a transmission line.
The functioning of an antenna depends upon the radiation mechanism of a transmission line.
A conductor, which is designed to carry current over large distances with minimum losses, is termed as a transmission line.
For example, a wire, which is connected to an antenna.
A transmission line conducting current with uniform velocity, and the line being a straight one with infinite extent, radiates no power.
For a transmission line, to become a waveguide or to radiate power, has to be processed as such.
These are especially used for the microwave transmission or here />The power from the transmission line travels through the waveguide which has an aperture, to radiate the energy.

In this modern era ofmany engineers are showing interest to do specialization in communication fields, but this requires basic knowledge of fundamental communication concepts such as types of antennas, electromagnetic radiation and various phenomena related to propagation, etc.
In case of wireless communication systems, antennas play a prominent role as they convert the electronic signals into electromagnetic waves efficiently.
Types of Antennas Antennas are basic components of any as they provide interconnecting links between transmitter and free space or between free space and receiver.
Before we discuss about antenna types, there are a few properties that need to be understood.
Apart from these properties, we also cover about different types of antennas used in communication various types of patch and slot antenna in detail.
An antenna with a higher gain is more effective in its radiation pattern.
Antennas are designed in such a way that power raises in wanted direction and decreases in unwanted directions.
The power received by the antenna gets associated with collective area.
This collected area of an antenna is known as effective aperture.
It may be considered as the capability of an antenna to direct radiated power in a given direction.
It can also be noted as the ratio of the radiation intensity in a given direction to the average radiation intensity.
Bandwidth is one of the desired parameters to choose an antenna.
It can be defined as the range of frequencies over which an antenna can properly radiates energy and receives energy.
Polarization: An electromagnetic wave launched from an antenna may be polarized vertically and horizontally.
If the wave gets polarized in the vertical direction, then the E vector is vertical and it requires a vertical antenna.
If vector E is in horizontal way, it needs a horizontal antenna to launch it.
Sometimes, circular polarization is used, it is a combination of both horizontal and vertical ways.
Effective Length: The effective length is the parameter of antennas that characterizes the efficiency of the antennas in transmitting and receiving electromagnetic waves.
Effective length can be defined for both transmitting and receiving antennas.
The effective length of the transmitter can be defined as the length of the free space in conductor, and current distribution across its length generates same field intensity in any direction of various types of patch and slot antenna />In case of a transmitting antenna, this is a plot that discusses about the strength of the power field radiated by the antenna in various angular directions as shown in the plot below.
A plot can also be obtained for both vertical and horizontal planes — and, it is also named as vertical and horizontal patterns, respectively.
Till now we have covered the properties of antennas, and now we will discuss on different types of antennas that are used for different applications.
Log-Periodic Antennas Log Periodic Antenna A log-periodic antenna is also named as a log periodic array.
It is a multi-element, directional narrow beam antenna that works on a wide range of frequencies.
This antenna is made of a series of dipoles placed along the antenna axis at different space intervals of time followed by a logarithmic function of frequency.
Log-periodic antenna is used in a wide range of applications where variable bandwidth is required along with antenna gain and directivity.
Bow-Tie Antennas Bow Tie Antenna A bow-tie antenna is also known as Biconical antenna or Butterfly antenna.
Biconical antenna is an omnidirectional wide-band antenna.
According to the size of this antenna, it has low- frequency response, and acts as a high-pass filter.
As the frequency goes to higher limits, away from the design frequency, the radiation pattern of the antenna gets distorted and spreads.
Most of learn more here bow-tie antennas are derivatives of biconical antennas.
The discone is as a type of half-biconical antenna.
The bow-tie antenna is planar, and therefore, directional antenna.
Log-Periodic Dipole Array Log Periodic Dipole Antenna The most common type of antenna used in is a log-periodic dipole array fundamentally comprises a number of dipole elements.
These dipole-array antennas reduce in size from the back end to the front end.
The leading beam of this RF antenna this web page from the smaller front end.
The element at the back end of the array is large in size with the half wavelength operating in a low-frequency range.
The spacing of the element gets reduced towards the front end of the array wherein the smallest arrays are placed.
During this operation, as the frequency varies, a smooth transition takes place along the array of the elements, which leads to form an active region.
Wire Antennas Wire Antenna Wire antennas are also known as linear or curved antennas.
These antennas are very simple, cheap and are used in a wide range of applications.
These antennas are further subdivided into four as explained below.
Dipole Antenna A dipole antenna is one of the most straightforward antenna alignments.
This dipole antenna consists of two thin metal rods with a sinusoidal voltage difference between them.
The length of the rods is chosen in such a way that they have quarter length of the wavelength at operational frequencies.
These antennas are used in designing their own antennas or other antennas.
They are very simple to construct and use.
The dipole antenna consists of two metallic rods through which current and frequency flow.
This current and voltage flow makes an electromagnetic wave and the radio signals get radiated.
The antenna consists of a radiating element that splits the rods and make current flow through the center by using a feeder at the transmitter out that takes from the receiver.
The different types of dipole antennas used as include half read article, multiple, folded, non-resonant, and so on.
Short-Dipole Antenna: Short Dipole Antenna It is the simplest of all types of antennas.
It does take any consideration about the absolute size of the dipole antenna.
The short dipole antenna is made up of two co-linear conductors that are placed end to end, with a small gap between conductors by a feeder.
A Dipole is considered as short if the length of the radiating element is less than a tenth of the wavelength.
The short dipole antenna is infrequently satisfactory from an efficiency viewpoint because most of the power entering this antenna is dissipated as heat and resistive losses also become gradually high.
Monopole Antenna A monopole link is half of a simple dipole antenna located over a grounded plane as shown in the figure below.
The radiation pattern above the grounded plane will be same as the half wave dipole antenna, however, the total power radiated is half that of a dipole; the field gets radiated only in the upper hemisphere region.
The directivity of these antennas become double compared to the dipole antennas.
The monopole antennas are also used as vehicle mounted antennas as they provide the required ground plane for the antennas mounted above the earth.
Loop Antenna Loop Antenna Loop antennas share similar characteristics with both dipole and monopole antennas because they are simple and easy to construct.
Loop antennas are available in different shapes like circular, elliptical, rectangular, etc.
The fundamental characteristics of the loop antenna are independent of its shape.
They are widely used in communication links with the frequency of around 3 GHz.
These antennas can also be used as electromagnetic field probes in the microwave bands.
The circumference of the loop antenna determines the efficiency of the antenna as similar to that of dipole and monopole antennas.
These antennas are further classified into various types of patch and slot antenna types: electrically small and electrically large based on the circumference of the loop.
The radiation resistance of small loop antennas can be improved by adding more turns.
Multi-turn loops have better radiation resistance even if they have less efficiency.
Small Loop Antenna Due to this, the small loop antenna are mostly used as receiving antennas where losses are not mandatory.
Small loops are not used as transmitting antennas due to their low efficiency.
Resonant loop antennas are relatively large, and are directed by the operation of wavelength.
They are also known as large loop antennas as they are used at higher frequencies, such as VHF and UHF, wherein their size is convenient.
They can be viewed as folded-dipole antenna and deformed into different shapes like spherical, square, etc.
Travelling Wave Antennas Helical Antennas Helical antennas are also known as helix antennas.
They have relatively simple structures with one, two or more wires each wound to form a helix, usually backed by a ground plane or shaped reflector and driven by an appropriate feed.
The most common design is a single wire backed by the ground and fed with a coaxial line.
In General, the radiation properties of a helical antenna are associated with this specification: the electrical size of the structure, wherein the input impedance is more sensitive to the pitch and wire size.
Helical Antenna Helical antennas have two predominate radiation modes: the normal mode and the axial mode.
The axial mode is used in a wide range of applications.
In the normal mode, the dimensions of the helix are small compared to its wavelength.
This antenna acts as the short dipole or monopole antenna.
In the axial mode, the dimensions of the helix are same compared to its wavelength.
This antenna works as directional antenna.
Yagi-Uda Antenna Yagi-Uda Antenna Another antenna that makes use of passive elements is the.
This type of antenna is inexpensive and effective.
It can be constructed with one or more reflector elements and one or more director elements.
Yagi antennas can be made by using an antenna with one reflector, a driven folded-dipole active element, and directors, mounted for horizontal polarization in the forward direction.
Microwave Antennas The antennas operating at microwave frequencies are known as.
These antennas are used in a wide range of applications.
Rectangular Micro strip Antennas Rectangular Micro strip Antennas For spacecraft or aircraft applications — based on the specifications such as size, weight, cost, performance, ease of installation, etc.
These antennas are known as rectangular microstrip antennas or patch antennas; they only require space for the feed line which is normally placed behind the ground plane.
The major disadvantage of using these antennas is their inefficient and very narrow bandwidth, which is typically a fraction of a percent or, at the most, a few percent.
Planar Inverted-F Antennas A Planar Inverted-F Antenna can be considered as a type of linear Inverted F antenna IFA in which the wire radiating element is replaced by a plate to increase the bandwidth.
The advantage of these antennas is that they can be hidden into the housing of the mobile when compared to different types of antennas like a whip, rod or helical antennas, etc.
The other advantage is that they can reduce the backward radiation towards the top of the antenna by absorbing power, which enhances the efficiency.
They provides high gain in both horizontal and vertical states.
This feature is most important for any kind of antennas used in wireless communications.
Reflector Antennas Corner Reflector Antenna Corner Reflector Antenna The antenna that comprises one or more dipole elements placed in front of a corner reflector, is known as corner-reflector antenna.
The directivity of any antenna can be increased by using reflectors.
In case of a wire antenna, a conducting sheet is used behind the antenna for directing the radiation in the forward direction.
Parabolic-Reflector Antenna The radiating surface of a parabolic antenna has very large dimensions compared to its wavelength.
The geometrical optics, which depend upon rays and wavefronts, are used to know about certain features of these antennas.
Certain important properties of these antennas can be studied by using ray optics, and of other antennas by using electromagnetic field theory.
Parabolic Antenna One of the useful properties of this antenna is the conversion of a diverging spherical wavefront into parallel wave front that produces a narrow beam of the antenna.
The various types of feeds that use this parabolic reflector include horn feeds, Cartesian feeds and dipole feed.

Types of Antenna Antenna Types for wireless communication This page covers various types of antenna used for wireless communication.
Antenna types include horn antenna, parabolic antenna, helical antenna, slot antenna, dielectric antenna, patch antenna, phased array antenna, dipole antenna, directional antenna, folded dipole antenna, ground plane antenna, YAGI antenna, Log periodic antenna etc.
Horn Antenna Horn antenna is regarded as flared waveguide.
It can work more efficiently along with parabolic reflector as found in dish antenna.
Normal waveguide if used for transmission of E-M waves it will not tightly coupled with free space impedance and results in reflected power and standing waves.
The mismatches are avoided by flaring the end of waveguide which creates horn antenna.
The more gradual the flare, better is the matching and lesser the losses.
This results in greater gain and directivity.
Depending upon the flaring there are different horn antenna types viz.
Gain of the pyramidal horn is summarized below.
A is the aperture of visit web page in meter 2 λ is the wavelength in meters Hor.
It is made of metal or screen mesh.
As shown in the figure, during transmission EM-waves fall on to the wide dish and gets radiated into the air, while during reception EM- waves fall on to the dish and gets focused to the horn antenna.
Aperture of the parabola antenna is the area of outer circle of the parabola.
About 6-8 turns are usually used in this type of antenna.
Ground plane reflector behind helix of shape circular or square is used.
Gain and beamwidth of this helical antenna is about 12-20 dB and 12-45 degree respectively.
Slot Antenna It is formed by cutting the metal sheet or waveguide about half wavelength in size.
Due to this cutting of the slot it is known as slot antenna.
Several slots can also various types of patch and slot antenna cut to form slot antenna array.
Array antenna usually will have better gain and directivity compare to single slot antenna.
Slot antennas are widely used in high speed aircraft by filling the slot with insulating material to create smooth surface.
Other external antennas will not be convenient to use at such high speed of the aircraft.
Dielectric Antenna They are made of polystyrene or using plastic or other dielectric materials.
These lens antennas are used for millimeter wave frequency above 40 GHz.
In this kind of antenna dielectric lens is placed over end of the horn antenna which focuses waves into narrower beam.
This results in greater gain as well as directivity.
Microstrip Patch Antenna This antenna type is made with microstrip based design on PCB.
Hence it is called as microstrip patch antenna.
This antenna is basically circular or rectangular area of copper separated by conducting ground plane.
Between this there will be insulating surface.
In the case of rectangular antenna, width is approx.
Phased Array Antenna Phased array antenna is casino and lanes using multiple antennas on a common PCB or plane.
The antennas used here are patch various types of patch and slot antenna or dipole antennas in a array.
This combination of multiple antennas help improve gain as well as directivity.
Individually all the antennas of the array are controlled and hence EM waves can be radiated in the different directions as desired.
The same concept is applied in YAGI antenna and parabolic dish antenna used for TV reception.
There are two types of arrangement designed in this type of antenna.
In one of this type of configuration, all the antennas are fed from common transmitter or receiver.
In the other type of configuration, low various types of patch and slot antenna transmitter amplifier or LNA is used with each of the array antennas.
Dipole Antenna Antennas radiate effectively when length of antenna is directly related to transmitted signal wavelength.
Dipole antennas are available in half wave or quarter wavelength in sizes.
In order to send and receive in particular direction requires antenna with high directivity.
This type of antenna having radiation pattern limited to narrow horizontal range is called directional antenna.
In order to design this visit web page of antenna two or more antennas are combined which make an array.
This increases gain and directivity.
There are two array antenna types viz.
Folded Dipole Antenna This type of antenna is popular due to its impedance which is about 300 Ohm.
The folded dipole antenna is made of 300 Ohm twin lead having length equal to one half wavelength.
Their ends are soldered.
This is variation of the standard half wavelength dipole antenna.
As shown in the figure, two parallel conductors are connected at the ends, with one side open at the center.
This central open part is interfaced wih transmission line.
Spacing between conductors is inverse proportional to frequency.
For low frequency application, spacing is about 2 or various types of patch and slot antenna in.
For high frequency application,spacing is about 1 in.
Ground Plane Antenna When vertical polarization and omni directional pattern is needed, ground plane antenna can also be replacement to standard half-wave dipole antenna.
This antenna is fed with coaxial cable.
It is formed by center conductor connected to the the vertical radiator and shield connected to the earth ground.
This generates vertical omnidiractional radiation pattern.
The vertical ground plane antennas are widely used in cars,trucks,boats and other vehicles.
The impedance of this vertical ground plane antenna is about 36.
As no coaxial cable exists at this impedance, standard 50 Ohm cable is used which generates mismatch of about 1.
YAGI Antenna YAGI antennas were widely used for TV reception, but as they are designed for one frequency only, they are not suited for wide frequency range.
YAGI antennas are made of one driven element, one reflector and one or more directors.
They are made with aluminium tubes and aluminium cross member.
Log Periodic Antenna The benefit of this log periodic antenna is its wide bandwidth application.
It is formed by different length driven elements.
The longest and shortest elements are of half wavelength long at lowest and highest frequency of interest.
reno 18 and over casinos elements of this log periodic antenna are fed with transmission line segments.
The phases of the signals sent to different elements various types of patch and slot antenna properly set to achieve high directivity and the best various types of patch and slot antenna />Antenna types related links.

It is also-called printed antenna.
It has two dimensional physical geometry.
The simplest patch antenna uses a patch which is one-half wavelength long, so that the metal surface acts as a resonator similarly to the.
A patch antenna is usually fabricated by mounting a shaped metal sheet on an insulating dielectric substrate, such as a printed circuit board, with a continuous various types of patch and slot antenna layer bonded to the opposite side of the substrate which forms a ground plane.
Hence it is easy to design and inexpensive to manufacture.
Some patch antennas do not use a dielectric substrate and instead made of a metal patch mounted above a ground plane using dielectric spacers.
The resulting structure is less rugged but has a wider bandwidth.
Patch antennas can be designed from the to as high as 100 GHz.
Common patch antenna shapes are square, rectangular, circular and elliptical.
However the shape is not restricted.
Any continuous shape is feasible.
Patch antennas are mechanically rugged and can be shaped to conform to the curving skin of a vehicle.
They are often mounted on the exterior of aircraft and spacecraft, or are incorporated into mobile radio communications devices.
They have high diversity and can be used for multiple feed points.
Microstrip antennas occurred during the 1980s.
Initially it was a military various types of patch and slot antenna, at the cost did not matter.
In the 1990s this technology has also been adopted for devices for communication as a low-cost technology.
But the performance of a microstrip array was well below that of a reflector antenna.

strain. Different types of antennas have been explored for strain sensing, such as circular patch antenna (Daliri et al. 2012) and slotted patch antenna (Salmani et al. 2011). Although these antenna sensors demonstrate promising strain measurement results, the application is very limited due to lack of proper signal modulation scheme

Hence, various types of monopole-like slot antennas have been investigated in recent years [5–9]. The UWB characteristic is obtained by an M-shaped radiation patch together with a rectangular slot ground plane in [5]. With a stepped stairs extended ground stub around the hexagonal monopole antenna, a relative bandwidth of 133% is accomplished.

A patch antenna is literally a patch of metal or other conductor on a flat surface.
There may or may not be a ground plane on the other side of the substrate.
The directionality, gain, polarization, and impedance are a function of the size and shape, and placement of the feed line.
Most GPSs use a patch antenna.
Thanks to Dii dot Unimore dot IT for the image: They don't have to be rectangular, they can even be circularly polarized.
Thanks to CST dot Com for the image and website describing the design and testing of this circularly polarized patch antenna: A slot antenna is a slot in a flat piece of metal or other conductor.
It can be thought of as sort of the complementary version of a dipole.
It can be fed in a number of ways.
One common way is to place slots in a waveguide.
With the right placement and spacing, a number of slots more info act as a directional and effective antenna.
Or it may be a slot in the ground plane on a PCB with the signal fed to the center edges, often a bit off center to match impedances.
Whereas the polarization of a dipole antenna is the same as the orientation of the elements, a slot antenna has a polarization 90 degrees from the orientation of the slots.
Thanks to ECE dot Illinois dot EDU: Here is a strange one.
A Vivaldi slot antenna, aka tapered slot.

Thanks to RadarTutorial dot EU: Thanks to Wikipedia dot Org for this combination of a Vivaldi tapered slot and horn antenna with remarkable bandwidth from 800MHz to 18GHz: Some slot antennas look more like a complementary version of a patch antenna.
Here is a circularly polarized slot antenna that is a round hole fed with two feeds 90 degrees out of phase.

AntDevCo employees have designed andmanufactured spacecraft microstrip patch antennas for many small spacecraft programs.
The antennas can be supplied with LHCP, RHCP, or linear polarization.
Figure shows that :A microstrip patch that uses a thicker substrate is more efficient.
In addition, as the substrate thickness increases, the radiation Q of the antenna decreases.
Thus, impedance bandwidth increases with increasing substrate thickness.
