The designed antenna is placed on a material called FR-4(flame retardant) whose dielectric constant Ɛr equals to 4.4 and the size of the substrate is 50mm×68mm. This antenna is simulated; a return loss of -15 dB and a gain of 8dB are obtained. The antenna can be used for Wireless Local Area Network application. The S-shaped DGS units are etched away from ground plane between microstrip antenna elements to reduce mutual coupling between antenna elements which operates at a frequency of 5.2GHz. Addition of slit wall in the ground plane that acts as an filter sandwiched between microstrip antenna elements to diminish mutual coupling. This method has achieved a mutual coupling reduction of -20 dB at resonant frequency.
