Optimization of patch antenna has always been an area of interest for design engineers; though size/SAR reduction, gain enhancement and efficiency improvement are the key constraints which must be addressed primarily. As patch antenna establishes its physical attributes on a dielectric substrate having effective electrical and magnetic properties, so selecting a correct substrate is important as well. In this paper, effect of substrate properties on the performance of microstrip patch antenna is presented. Proposed geometry has been optimized to achieve a useful impedance bandwidth from 2.30 to 2.46GHz at VSWR less than or equal to 2.
