Ansari, Kamakshi Kumari, Ashish Singh, Anurag Mishra] In this paper, a comparative study of co-planar gap coupled rectangular and elliptical microstrip patch antenna is presented. It is analyzed by using circuit theory concept. The proposed antennas show ultra wideband operations which depend on dimensions of the patches, gap between them as well as air gap thickness. It is observed that the performance of gap coupled elliptical patch antenna is better than that of rectangular patch antenna while the area of rectangular and elliptical patches is same. The bandwidth of proposed rectangular patch antenna is found to be 50.7% with average gain of 6.5dBi while for elliptical patch antenna the bandwidth and gain further improves up to 57.6% and 9.5dBi respectively. The theoretical results are in good agreement with the simulated results obtained from IE3D simulation software.
