Paper Title
Reduction of Mutual Coupling on Two Element Array Antenna

Recently many radar systems are based on microstrip array antennas since they have clear benefits over classical ones. Unfortunately, the side lobes of microstrip array antenna have still enough energy and under some conditions, they are able to propagate along the surface, known as surface waves, that can increase the coupling of energy between array elements, so-called mutual coupling. In this paper, a high impedance surface Jerusalem cross electromagnetic band gap (JC-EBG) structure is proposed to reduce mutual coupling and improve isolation between antenna elements. The results of the simulation program have shown that the isolation between the antenna elements can be improved with the help of the proposed structure.
