This paper presents a compact MIMO antenna of 2-port having placed orthogonally for upcoming 5th generation mm-wave application. The single unit cell of the proposed MIMO antenna system consists of an elliptical patch as a radiator with a dimension of 2.1 x 1.1 mm2 (a x b ) using a microstrip feed line of 50-ohm for impedance matching. Roggers RT5880 is used as a substrate material with a standard thickness of 0.254 mm and a total dimension of 9 x 8 mm2 (Lx W). It is observed from the simulation that a single antenna element operating from 29.6—44.2 GHz, wide impedance bandwidth of 14.6 GHz, and -25.8 dB return loss at a central frequency of 38.7 GHz. Furthermore, a 2-port MIMO antenna system is utilized for increased channel capacity and high diversity polarization. For MIMO transformation, the same single unit cells are arranged orthogonally for mitigating mutual coupling. The total geometry of the proposed design is 8 x 15 mm 2 having a compact size and offering a wide impedance bandwidth of 16 GHz, low isolation coefficient of -17 dB, high gain, efficiency, low ECC, and high diversity gain. However, all the simulated outcomes for the proposed design are valid and consider good candidate.The overall geometry of the proposed MIMO.
