Microstrip patch antenna has certain drawbacks of low gain, narrow band, and surface wave losses. In this paper the solution method used is a patch array with SRR metamaterial, which reduces the mutual coupling between the patch elements, thereby improving the directive gain and reducing the surface waves. A rectangular microstrip patch antenna that meets the requirement of operation at (8.29 GHz), the proposed configurations are simulated and analyzed in Ansoft High Frequency Structure Simulator. The VSWR, radiation patterns for gain and S11 performance are used for the analysis of the final design. Feed point on the patch that gives a good match of 50 ohm, input impedance was found by a method of trial and error.
