Four Element MIMO Antenna System Based on SRR Loaded Printed Monopoles for 28/38 GHz 5G Applications

Abstract

This document discusses design of a four-element MIMO antenna system deploying split ring resonator (SRR) loaded printed monopoles for millimeter wave 5G applications i.e. at 28/38 GHz. Two similar sized electrically small split ring resonator (SRR), loaded on either side of the printed monopole constitutes the fundamental single antenna element radiating efficiently at 28 and 38 Gigahertz bands. Excellent radiation and impedance characteristics are observed in these both bands when a 4-element MIMO antenna was implemented by deploying the fundamental antenna element. The fabrication and experimental results of the design presented herein are in progress. The antenna proposed here has portrayed 2.2 Gigahertz and 1.2 Gigahertz of impedance bandwidth centered at 28 Gigahertz and 38 Gigahertz respectively, exhibited satisfactory low Envelope Correlation Coefficient and mutual coupling. This antenna can better play the part as a potential candidate for 5G base station applications.
