Abstract

The design of electromagnetic band gap (MEBG) to reduce the mutual coupling effect on array antenna is proposed in this paper. The proposed design model of EBG structure is mushroom like EBG (MEBG). The MEBG design is used for microstrip array antenna at frequency S-band radar antenna. Reducing the mutual coupling effect is expected to increase the sidelobe level (SLL) performance. The proposed MEBG structure is placed between the patch elements to reduce mutual coupling effect of each element at a distance of λ/2. The simulation results for the proposed design shown slightly reduce the mutual coupling and an increase SLL performance compared to array antenna without MEBG. © 2018 IEEE.
