1.1 Overview:
In antenna theory of analysis and design, the most forward looking topic is microstrip patch antenna. Microstrip patch antennas are made to have many different geometrical shapes and dimensions but among all the shapes of microstrip patch, four of them are most common than another that are square, rectangular, dipole and circular. They are employed in wide range of modern applications because of their easiness to design and compatibility with printed-circuit technology.
The basic form of microstrip patch antenna is consists a patch and a ground plane that are separated by dielectric substrate as shown in Figure 1.1. The surface of the bottom side of a thin dielectric substrate is fully covered with metallization that act as a …show more content…
The most common conducting materials that can be used for the patch is gold or copper. The feed lines and the radiating patch are usually embedded on the dielectric substrate by using photo etching process. Due to fringing fields induced between the patch edges by various methods microstrip patch antenna radiate primarily. So due to fringing fields the dimensions of the patch electrically seemed a bit larger than its actual physical dimensions. 1.2 Types of Microstrip Patch Antenna
According to the physical parameters, there are so many different types of microstrip patch antennas such as square, rectangular, dipole, circular, triangular, circular ring, elliptical or any other configuration. These are illustrated in Figure 1.2. Figure 1.2: Common shapes of microstrip patch. The widely used shape of patch is rectangular due to its easiness in fabrication and analysis. This type is also robust design and very easy to handle.

The radiation pattern is wonderfully described in the form of a three dimensional graph of power versus elevation and azimuth angles but more generally defined by E-plane or H-plane where one angle is held fixed while the other is varied as shown in Figure 1.4.1. Figure 1.4.1: A radiation pattern for a microstrip antenna.
The radiation pattern can be determined easily which a microstrip patch antenna has. The source of the radiation of the electric field at the gap of the edge of the microstrip element and the ground plane is the key factor to the accurate estimation of the patch antenna.
1.4.2 Return Loss
Return loss is an essential parameter when associating an antenna. It is a manner to characterize the input and output of signal sources. The return loss is interrelated to impedance matching and the maximum transfer of power theory. When the load is not matched, that means all the available power from generator is not delivered to the load. This return loss is also a measure that how much power is deliver from source to the
