New compact MIMO antenna for 5G, WiMAX and WLAN technologies with dual polarisation and element diversity

Abstract

Abstract A new MIMO antenna configuration, with two different elements is proposed. The first element with a T‐shaped monopole is fed by a microstrip line and the second element is a square patch fed by electromagnetic coupling. The antenna configuration is used to provide good decoupling between the elements and to ensure antenna diversity. The antenna is designed to operate in the UWB 3.1–5.2 GHz lower‐band technology and also in the lower band of 5G technology at 3.5 GHz. The antenna design steps are presented and discussed. Simulation and design are performed using Ansoft HFSS software and the generalisation of the wave concept iterative procedure (WCIP) modified to account for the MIMO antenna structure analysis. A prototype is fabricated for comparison purposes and good agreement is observed between simulation and measurement results.
