Two Port Compact CPW-Fed wideband Multiple Input Multiple Output Dielectric Resonator Antenna for WLAN Application

In this article, a CPW-fed two-port compact MIMO (Multiple Input Multiple Output) antenna is investigated. The proposed antenna contains two cylindrical dielectric resonators (CDRs) of the same size. These two radiators are excited by the Co-Planar Waveguide (CPW) feeding mechanism. The compactness of the proposed antenna is achieved by placing the CDRs at a distance that is smaller than the operating wavelength. This antenna achieves 20.7% fractional bandwidth and high port-to-port isolation of - 31.8dB. Various MIMO diversity metrics are evaluated and noticed to be within the required limit. The antenna proposed in this article is suitable for WLAN application.
