Abstract

This paper proposes a four-port multiple-input multiple-output (MIMO) antenna for 5G communication. The reference hexagonal antenna with WI-FI slots is designed on FR-4 substrate. Next, four reference antennas are arranged orthogonal to each other for reduction of isolation. The overall dimensions of WI-FI slot four port MIMO antenna is 60×60×1.6 mm³, and it is implemented on an FR-4 substrate with defective ground structure. With an impedance bandwidth of 1 GHz(Giga Hertz), the suggested MIMO antenna operates in the frequency range of 3.3 to 4.3 GHz. The mutual coupling is more than 23 dB among all ports. Furthermore, the MIMO antennas' channel capacity loss (CCL), diversity gain (DG), and envelope correlation coefficient (ECC) are estimated. The parameters are measured using anritsu MS2037C Vector Network Analyzer(VNA).
