Abstract

A four-element circular patch multiple input multiple output (MIMO) antenna is designed operating at sub-6 GHz frequency for 5G applications. The proposed design of antenna achieves better performance with 85% of measured efficiency and peak antenna gain of 5 dB. Further, an envelope correlation coefficient of 0.00052 with the diversity gain of 9.99 dB is achieved. The MIMO antenna of size 72 × 27 mm which consists of four identical circular patches with a mean effective gain (MEG) < 3 dB. Each patch of the antenna with a circular slot is separated by a stub. It offers better isolation and matching, which helps to achieve wider impedance bandwidth. A shorted T-shaped stub and two I-shaped stubs are created to achieve the isolation of more than 37 dB at 3.8 GHz for 5G applications.
