A novel compact design for bandwidth enhancement of rectangular microstrip array is presented in this paper. The basis for achieving the bandwidth enhancement is through metamaterial structure. Two types of metamaterial namely EBG and DSG are studied. Metamaterial structures are used for further antenna performance improvement, which suppress surface waves and improve the design characteristics. In this paper, two cross slots cuts in the ground plane, which enhances the bandwidth of reference antenna. This shape produces bandwidth ranging from 15.30 GHz to 17.66 GHz, gives impedance bandwidth of 2.3649 GHz, whereas reference antenna without DSG is having impedance bandwidth of 290MHz.
