In this article, we introduce a novel design of a tri-band two-element MIMO antenna, powered by a microstrip line. This precisely designed antenna incorporates radiators symmetrically arranged on the Rogers RT5880 substrate, displaying optimized dimensions of 31×11×0.8 mm3. Our approach is characterized by the addition of a comb-shaped etched motif on each rectangular patch element. This feature has demonstrated its effectiveness to operate at frequencies of 24 GHz, 31 GHz, and 36 GHz. In detail, the 24 GHz band is particularly suited for high-quality satellite communications, the 31 GHz frequency is suitable for high-resolution radar applications, and the 36 GHz band is optimized for high-velocity point-topoint communication links. On the other hand, the prototype of the proposed MIMO antenna is simulated, and the mutual coupling between the ports is less than 21 dB. Consequently, the antenna performance metrics, such as the Envelope Correlation Coefficient (ECC) is less than 0.01 with a maximum Diversity Gain (DG) of about 9.95 dB, and the antenna maintains high efficiency of up to 94% across the entire operational band. Additionally, the MIMO antenna exhibits a gain of 7.26 dBi, 6.82 dBi, 7.26 dBi respectively, affirming this MIMO antenna as an excellent candidate for multi-band applications within the realm of fifth-generation wireless communications.
