Four-Port Cylindrical DRA based MIMO Antenna for WLAN Application

Abstract

This paper presents a C-shape aperture coupled four-port cylindrical dielectric resonator (DR) based multiple input multiple output (MIMO) antenna. The proposed geometry consists of four orthogonally placed CDRAs, to achieve minimum isolation of -28dB between the ports. The size of CDRAs is chosen such that it covers the frequency range 5.09GHz – 5.93GHz for the 5.62GHz WLAN application. Two orthogonal modes and were excited in the CDRAs by incorporating a C-shaped aperture.
