ABSTRACT The study presents a compact four‐port dual‐band MIMO antenna specific to millimeter‐wave (mm‐Wave) 5 G networks that operate at higher frequency intervals of 26 and 39 GHz. The development process of MIMO antennas that operate at higher frequencies is highly challenging, mainly because of the need to simultaneously achieve wider bandwidth, larger radiation efficiency, and lower mutual coupling within a compact structure. To address these challenges, the proposed antenna employs four as
