Hexagonal DRA with Complementary E-Shaped DGS For Mutual Coupling Reduction

Abstract

A complementary E-shaped ground plane structure which can reduce mutual coupling between two hexagonal dielectric resonator antennas is proposed in this paper. The antennas are operating at resonant frequency 12.59 GHZ. Using ROGGERS substrate with Alumina (99.5%) lossy as DRA material, the proposed antenna is designed. The proposed design has improved it’s performance in parameters like bandwidth, VSWR and gain at resonant frequency and working frequency is in the range of 11-14 GHZ. It provides mutual coupling reduction up to 21.76 dB and return loss of -37.44 dB at a frequency of 12.59 GHZ. The proposed antenna is used in satellite communications and radar applications.
