Abstract

In this paper, we design, fabricate, measure, and report two proposed multiple input multiple output antenna elements (MIMOs) with good performance in the 5G band. The MIMO antennas are mounted on Roger / Druoid 5880 substrates (dielectric constant: 2.2) with an overall structure volume 20×24.14×0.79mm3. First, a comprehensive parametric study is performed based on CST Electromagnetic (EM) Simulator to investigate and enhance the antenna performance in relation to 5G application requirements. Second, as part of the antenna design process, we compute the envelope correlation coefficient (ECC > 0.01dB) and diversity gain (DG> 9.9dB) and achieve good results. Third, we provide fabrication and measurement verification with good agreement. Fourth, we use a tapered feed structure with inset feed to minimize mutual coupling and achieve matching along 2 transmission lines with various impedances with high compactness in the antenna structure. Fifthly, we report that the proposed antenna structure has a gain is 8 dBi (dB) at the relevant operating frequency band (24.25
