Abstract
This paper presents the design, fabrication, measurement, and evaluation of two multiple input multiple output antenna elements (MIMOs) optimized for performance in the 5G frequency band. The MIMO antennas are integrated onto Roger/Druoid 5880 substrates with a dielectric constant of 2.2, housed within a compact volume measuring 20×24.14×0.79mm3. Initially, a thorough parametric study is conducted using the CST Electromagnetic (EM) Simulator to analyze and optimize the antenna's performance according to 5G application requirements. Subsequently, in the antenna design phase, calculations are made for the envelope correlation coefficient (ECC > 0.01dB) and diversity gain (DG > 9.9dB), yielding favorable outcomes. Fabrication and measurement procedures are carried out to verify the antenna's performance, demonstrating good agreement between simulation and experimental results. Additionally, a tapered feed structure with inset feed is employed to minimize mutual coupling and ensure matching along two transmission lines with various impedances, achieving high compactness within the antenna structure. Furthermore, the paper reports that the proposed antenna structure attains a gain of 8 dBi (dB) within the relevant operating frequency band (24.25 GHz).
