Abstract

In this paper, a four-element MIMO antenna with slots and partial ground plane for 5G communication systems operating at C-band (3.4GHz - 3.8GHz) is presented. It is designed on Rogers RT/Duriod 5880 with a dielectric constant and thickness of 2.2 and 0.787mm, respectively. The dimensions of the slots and the partial ground plane are optimized by applying a heuristic search algorithm, the Hill Climbing, to increase the impedance bandwidth and reduce the mutual coupling between the antenna elements without using a decoupling structure or extra spacing. It achieves a huge bandwidth of 539.4MHz covering 3.2926GHz to 3.832GHz at S 11 ≤ -10dB and resonates at 3.595GHz with a reflection coefficient and mutual coupling of -46.45dB and <; -16dB, respectively. It also achieves an envelope correlation coefficient (ECC) of <; 0.017, diversity gain (DG) of ~10dB and channel capacity loss (CCL) of <; 0.18bits/sec/Hz throughout the operating frequency band, respectively.
