Mutual Coupling Reduction In Antenna Arrays Using Jerusalem Cross Periodic Structure

Abstract

When the number of antenna elements is placed in forming the arrays, mutual coupling between the antenna elements is a critical issue. A periodic structure is used to suppress mutual coupling between elements in a micro strip array In this paper, Jerusalem cross periodic structure is proposed as an effective solution for reducing mutual coupling in a micro strip array antenna that consists of two elements. Applying the proposed periodic structure in the substrate and between the patches is simulated and studied. Simulation results show the improvement of mutual coupling by adding Jerusalem cross periodic structure to the antennasubstrate. © Research India Publications.
