In the present paper a micro strip patch antenna with DGS for GSM application is designed and simulated at 1.8 GHz frequency. DGS is applied in the shape of circular rings on the ground plane. Without DGS the return loss is -12 dB, which is further improved to -22dB by applying DGS. The simulated results such as impedance, bandwidth, directivity, gain and radiation pattern are analyzed and compared for with and without DGS.
