MIMO wireless technology can significantly improve the data rate and capacity of wireless systems through multipath data transmission and reception. MIMO systems are currently employed in 4G user equipment and show promise for use in future 5G mobile terminals. One of the promising frequencies, for sub-6-GHz MIMO 5G communications is 3.5, and 3.6 GHz, respectively. There are many requirements for antenna design, such as low-profile, bandwidth, ease of fabrication, and high isolation. To improve isolation and reduce mutual coupling between the adjacent microstrip-line feeding ports of the dual-polarized radiators, a pair of circular-ring/open-ended parasitic structures is embedded across each rectangular radiator. The size of the dual-polarized antenna is 25 × 25 × 1.6 mm³, with an impedance bandwidth of each antenna element (2.4× 10 mm2) is 500 MHz (3.35–3.85 GHz) and a realized gain of 3.03 dBi. In addition, the Specific Absorption Rate (SAR) and the radiation characteristics of the proposed design in the vicinity of the user's head are studied. The proposed antenna exhibits good features with potential applications for use in 5G mobile terminals. The proposed MIMO antenna is designed and simulated using CST MWS 2019 software.
