When a number of antennas are placed in an array formation, the mutual coupling between the array elements becomes a critical issue. The Microstrip Patch Antennas are useful in sending the onboard parameters to the ground, under different operating conditions. The main aim is to maintain the mutual coupling suppressing structure to the simplest form, while providing a great amount of reduction in the mutual coupling of patch antennas. The idea is to use a Defected Ground Structure (DGS), placed at the bottom of the substrate. It greatly reduces the mutual coupling between the antenna elements, thereby enhancing the antenna performance. The introduction of DGS does not affect other characteristics of the antenna array. The DGS and the normal patch antenna is simulated using CST (Computer Simulation Technology) antenna simulation software. Once an antenna design is finalized, their operational characteristics remains unchanged during the use.
