In this paper, the drawback of patch antenna was impedance bandwidth. For this purpose, rectangular microstrip patch antenna loaded with metamaterial structure has been proposed for improving the bandwidth by using CST microwave studio in this paper. The proposed antenna is designed at a height 3.2 from the ground plane by using CST microwave studio. The bandwidth of microstrip patch antenna is 12 .1MHz and return loss is -10.36dB at a band. The bandwidth of desired antenna is increased up 63.7MHz at 2.865GHz.
