Abstract: Array antennas are useful in military applications due to high gain and more directivity. But the individual elements of array radiation may interfere each other and resulting in Mutual coupling. In this research paper, Defected Ground Structure (DGS) is used to reduce the mutual coupling and further array of DGS is used for the optimization of output parameters. The proposed antenna of 1×2 array and 4×4 array of DGS is designed and simulated using HFSS software. It operates at 15GHz (Ku band) with minimum mutual coupling of -25dB. The gain is 8dB and VSWR and Return loss are in optimal Range. The output parameters are plotted and compared using MATLAB software.
