Compute and plot the reflection coefficient for this antenna over the band. In the process, the single wide response has been split into multiple narrow band regions catering to specific bands in the WiMAX standard. Some patch antennas do not use a dielectric substrate and instead are made of a metal patch mounted above a ground plane using dielectric spacers; the resulting structure is less rugged but has a wider bandwidth.

Microstrip antenna

In this paper, a design and analysis of Microstrip patch is presented. The proposed antenna has simple structure with U-slot operating for the application of Amateur radio[4]. The overall dimension of the antenna comes around The impedance matching and radiation characteristics of the designed structure are investigated by using MOM based commercially available electromagnetic solver IE3D.

The simulation results show that the antenna offers excellent performance for Amateur radio application ranging from 5. The proposed antenna gives directional pattern in the E plane and Omni directional radiation pattern in the H plane over the frequency range and relatively stable.

In times of crisis and natural disasters, Amateur radio is often used as a means of emergency communication when wire line, cell phones and other conventional means of communications fail. It uses designated radio frequency spectrum for purposes of private recreation, non-commercial exchange of messages, wireless experimentation, self-training, and emergency communication. Amateur radio operates in the frequency band 5.

In telecommunication , a microstrip antenna also known as a printed antenna usually means an antenna fabricated using microstrip techniques on a printed circuit board PCB. An individual microstrip antenna consists of a patch of metal foil of various shapes a patch antenna on the surface of a PCB, with a metal foil ground plane on the other side of the board. Most microstrip antennas consist of multiple patches in a two-dimensional array. The antenna is usually connected to the transmitter or receiver through foil microstrip transmission lines.

The radio frequency current is applied or in receiving antennas the received signal is produced between the antenna and ground plane. Microstrip antennas have become very popular in recent decades due to their thin planar profile which can be incorporated into the surfaces of consumer products, aircraft and missiles; their ease of fabrication using printed circuit techniques; the ease of integrating the antenna on the same board with the rest of the circuit, and the possibility of adding active devices such as microwave integrated circuits to the antenna itself to make active antennas.

The most common type of microstrip antenna is the patch antenna. Antennas using patches as constitutive elements in an array are also possible. A patch antenna is a narrowband, wide- beam antenna fabricated by etching the antenna element pattern in metal trace bonded to an insulating dielectric substrate, such as a printed circuit board , with a continuous metal layer bonded to the opposite side of the substrate which forms a ground plane.

Common microstrip antenna shapes are square, rectangular, circular and elliptical, but any continuous shape is possible. Some patch antennas do not use a dielectric substrate and instead are made of a metal patch mounted above a ground plane using dielectric spacers; the resulting structure is less rugged but has a wider bandwidth. Because such antennas have a very low profile, 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.

Microstrip antennas are relatively inexpensive to manufacture and design because of the simple 2-dimensional physical geometry. They are usually employed at UHF and higher frequencies because the size of the antenna is directly tied to the wavelength at the resonant frequency. A single patch antenna provides a maximum directive gain of around dBi. It is relatively easy to print an array of patches on a single large substrate using lithographic techniques. Patch arrays can provide much higher gains than a single patch at little additional cost; matching and phase adjustment can be performed with printed microstrip feed structures, again in the same operations that form the radiating patches.
