Abstract: “The microstrip patch antenna arrays are widely used in the wireless communication applications. Mutual coupling between the antenna elements affects the array performance, and reduction of the coupling and improvement of the isolation are important tasks for an array system. In this paper, some compact, metamaterial-based electromagnetic band gap (EBG) structures are proposed, which are an alternative to the existing EBGs used in various applications, to reduce the mutual coupling effect between the antennas in an array. The design is obtained by using a simulation program and the simulation results show that the isolation between the elements can be enhanced with the proposed EBGs.”
