In this research paper we proposed a new DGS design to improve the bandwidth of RMPA designed for 2.2GHz operating frequency. In this paper, author proposed a RMPA with DGS to enhance its parameters and mainly bandwidth and directivity of the antenna. To achieve a very important bandwidth and directivity enhancement author proposed a table shaped unsymmetrical DGS in the ground plane. This unsymmetrical DGS on the other side of the patch increases the fringing field which consequently increased the parasitic capacitance. This coupling of patch and ground made the bandwidth and directivity enhanced from the RMPA without DGS.
