Design and Simulation of Compact MIMO Antenna for the 5G Communication in C-Band

Abstract

This paper presents CPW fed 4 × 4 configurations "Multiple Input Multiple Output"(MIMO) antenna is proposed for 5th Generation New Radio (NR) Sub-6 GHz band. The antenna consists of four hexagonal-shaped antenna elements with an overall area of 61 × 61 × 1.6 mm3. The pattern diversity of the proposed MIMO is obtained by embedding an H-shaped stub in the ground plane and an I-shaped stub is integrated with the ground plane to obtain high isolation (<20 dB). The value of ECC for the proposed four-port antenna is less than 0.002. The proposed antenna covers the frequency band from 3.6 to 3.8 GHz (5G n78 band) effectively. The result guarantees the excellent diversity performance of the proposed four-port antenna. The performance of this antenna is examined in terms of port separations, DG, ECC, mean effective gain, CCL.
