In this paper analysis has been carried out for a circular microstrip patch antenna and software based design using three different shapes of substrate. Three individual antennas are designed and compared. A circular patch where radius 8.58 mm and thickness 0.02 mm put on three different substrate shapes like square, rectangular and circular. This type of design uses Roger RT/Duriod 5880 substrate material based on HFSSTM EM Simulator Software. The results of three antennas are compared in terms of return loss, VSWR and return loss bandwidth at particular frequency.
