SIW antenna for MIMO system

Abstract

This paper presents an SIW MIMO system antenna configuration. The paper is devoted to minimize the mutual coupling between antennas fed from different ports with the use of SIW structures. The paper discusses the system with and without introducing the SIW structure. The antennas are operating at 5GHz (Wi-Fi application). It contributes a mutual coupling reduction up to 16.6 dB. The antenna configuration is fabricated. It conducts a good agreement between the measured and simulated scattering coefficients. The antenna gain, and pattern are nearly unchanged for the different configurations.
