Abstract: A wideband microstrip antenna using parasitic patch element is proposed in this paper. Initially a circular patch antenna is designed. The antenna is found to resonate at 5.2 GHz and provides impedance bandwidth of 3.84 . To enhance the impedance bandwidth, two unequal rectangular parasitic patches are introduced along with the modified initial circular patch antenna which provides impedance bandwidth which ranges from 7.86 GHz to 10.60 GHz with 29.68 of impedance bandwidth .Suitable peak gain of 4.56 dBi is also achieved by the proposed antenna. This makes the antenna suitable for X band (8-10 GHz) application.
