In this paper, rectangular microstrip patch antenna (RMPA) along with metamaterial which has design of “slotted rhombus connected with rectangular shaped cover structure” is proposed at height of 3.2 mm from the ground plane. The RMPA with proposed metamaterial structure is designed to resonate at 2.7 GHz frequency. This work is mainly focused on increasing the potential parameters of microstrip patch antenna. Proposed metamaterial design structure significantly reduces the return loss and increases the bandwidth and directivity of the antenna as compared to RMPA alone. The bandwidth is increased up to 27.9 MHz in comparison to RMPA alone. The return loss of proposed antenna is reduced by 18 dB by incorporating the proposed metamaterial structure. For simulation purpose, CST-MWS software has been used.
