Abstract
A dual element tapered fed Multiple-input-multiple-output (MIMO) antenna with an impedance bandwidth of 5.14GHz (27.29-32.43 GHz) using a partial ground plane is proposed for 5G millimeter wave applications. The envelope correlation coefficient (ECC), diversity gain (DG), mean effective gain (MEG), total active reflection coefficient (TARC), and channel capacity loss (CCL) of the MIMO antenna are addressed, and the obtained values are 0.012, 9.98dB, 3dB, − 13dB, and 0.15 bits/sec/Hz, respectively. The maximum gain of 9.20dBi is achieved at 29GHz. Furthermore, in the frequency range of 27.29-32.43 GHz, a radiation efficiency of more than 93% is obtained. The proposed MIMO antenna is built on a Rogers RO 4003 substrate with a dielectric constant of 3.55, a loss tangent of 0.0027, and a dimension of 35×25×0. 76mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> .
