Day by day with the increasing of demand for long distance communication resulting in requirement of many antenna elements on a single structure and if we do so there is a problem of coupling between those elements which reduces the antenna efficiency. So a new methodology to improve the isolation in micro strip patch antenna arrays is described through the implementation of a slotted meander-line resonator (SMLR) which is creating defect in the micro strip structure. The resonator is designed to suppress the surface current between the two patch antennas coupled along H-plane and operating at a frequency of 5 GHz which is used in microwave links and airborne RADAR applications. The configuration has been designed, simulated and validated experimentally.
