This work introduces a high-performance multi-input multi-output (MIMO) antenna design to operate at the 28 GHz band. The proposed four-port MIMO antenna, in which each port comprises 1 × 8 series-fed array, achieves peak gains of 13 dBi along with bandwidths GHz. Enhanced performance is achieved through optimal spacing elements and decoupling methodology comprising well-designed metamaterial unit cell, leading reduced interference between arrays. shows significantly suppressed mutual coupling be less than −40 dB, diversity gain that very close 10 an envelope correlation coefficient 0.00012, channel capacity loss 0.147 bit/s/Hz, experimental assessments confirmed these developments, endorsing suggested as robust contender for 5G mmWave communications.
