Abstract: In this paper, proposed Rectangular microstrip patch antenna loaded with metamaterial structure is used for bandwidth improvement at dual band operation. 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 MHz and return loss is -10.36 dB at dual band. The bandwidth of desired antenna is increased up 22.8MHz at 1.824 GHz. and up 56.2 MHz at 2.85 GHz. The return loss of proposed antenna is reduced up to -36.922 dB at 1.824 GHz and up to -29dB at 2.85 GHz . This proposed design has small size, easy to fabricate and better directivity.
