Comparative analysis of microstrip antenna for high gain using FSS

The microstrip patch antenna has been designed with noncontact feeding method of aperture coupled microstrip patch antenna (ACMPA). In this study a comparative analysis of high gain antenna has been carried out. ACMPA has been designed with the rectangular shape of aperture coupling. Frequency Selective Surface has been incorporated to enhance the gain. Gain comparison has been done between ACMPA with and without FSS. It has been seen that the performance has been enhanced with FSS. All the simulation has been done using Ansoft HFSS. To validate the design performance parameters like return loss, gain and VSWR has been computed. Prototype has been designed for WiMAX application at 5.8 GHz.
