Microstrip antennas have received a lot of attention in the recent years because of their potential applications in many portable communication systems. There has been significant advancement in improving the inherent narrow operating bandwidth of microstrip antennas. Use of air gap between the substrate and the ground plane is an effective and convenient approach for improving the band width. Hence, in this paper an attempt has been made to study and develop a broad band microstrip antenna by creating an air gap between the ground plane and the dielectric substrate. The analysis has been done on a circular patch in microwave frequencies range of S and X band. Effect of air gap on band width has been studied and plotted. This can conveniently be applied to the array configuration of any geometry for much larger band gap achievement.

Keywords : Microstrip antennas, Bandwidth, Airgap circular patch.
