The proposed MIMO antenna system consists of four components operating at a dual-band (28/38 GHz) frequency through an antenna system with an angle of 90° to each other. A simulated impedance bandwidth (S11 < −10 dB) is obtained by the proposed antenna at frequency 28.81 GHz and 38.098 GHz is −15.83 dB and −11.87 dB, respectively, allocated to the 5G applications by the Federal Communications Commission. By using MIMO antenna system, capability and transmission speeds can improve in a communication system. The design of such antennas is important in visualizing the desired output/result with the aid of simulation and helps to achieve the necessary antenna outcomes for future work. The simulation effects help us to test certain parameters for the better performance specifications of the built device, such as return constraint, antenna isolation and bandwidth.
