A rectangular microstrip patch antenna (RMPA) along with metamaterial which has design of hexagonal rings-shaped cover structure is proposed at a height of 3.2 mm from the ground plane. The RMPA with proposed metamaterial structure is designed to resonate at 2.31 GHz frequency. This work is mainly focused on increasing the potential parameters of microstrip patch antenna. The proposed metamaterial structure significantly reduces the return loss and increases the bandwidth and directivity of the antenna as compare to RMPA alone. The bandwidth is increased u to 76 MHz in comparison to RMPA alone. The return of proposed antenna is reduced to 32.9 db.Keywords: Rectangular microstrip patch antenna (RMPA), hexagonal rings shaped cover metamaterial structure.
