Wideband antenna is highly demandable due to the dynamic development in the wireless technology. In this paper, we propose a new design of rectangular microstrip antenna based on the EBG Cell loading technique. By incorporating the Uniplanar Electromagnetic Band Gap (EBG) Cells on the ground plane of the rectangular microstrip Antenna, the enhanced performance of the antenna can be enhanced. Here we have studied and compared Conventional Rectangular Microstrip Antenna (CRMA) antenna performance with and without EBG cells. Comparison result shows that the bandwidth of CRMA is enhanced by loading EBG cells and the bandwidth increases to 62.45%. Also with EBG cells there is reduction in the back lobe radiations.
