Customized Rectangular Microstrip Patch Antenna for Enhanced Gain to operate at 7.5 GHz

The most inherent drawback of patch antenna is the reduction in gain. It happens due to flow of surface currents and low radiation efficiency. This paper aids in examination of various gain improvement techniques and the design of rectangular patch modified in a systematic way to obtain the desired gain by using rectangular and circular slots. The antenna designs are developed at 7. 5GHz which is applicable for satellite communications. The designs are developed in Ansys HFSS software and the various simulation results are obtained. From the simulation results, the various parameters are compared for the developed six designs and observation proves hybrid combination of slot structures as the well choice for practical implementation.
