These days patch antenna arrays are widely used in various communication systems. In this research design of miniaturized microstrip patch antenna array is presented. Miniaturization is achieved by reducing the mutual coupling between patch antenna elements. Complementary Split Ring Resonator is used to reduce the mutual coupling between patch elements in array. The mutual coupling between patch elements with and without resonator is calculated using High Frequency Structure Simulator. It has been observed that the mutual coupling between elements is reduced by 20 dB at 2.4 GHz by using resonator. Due to reduction in mutual coupling, patch antenna elements can be fabricated in less space which leads to compact antenna array system design. A miniaturization of 4.34% is achieved for two element Patch array without affecting the power gain and directivity of patch antenna array.
