This research presents a high-performance design for multiple-input multiple-output (MIMO) antenna intended operation within the 28 GHz band. The four-port MIMO configuration, featuring 1 × 8 series-fed arrays each port, has demonstrated peak gains of 15.5 dBi and bandwidths 2 GHz. improved performance results from carefully optimized spacing decoupling approach involving well-designed metamaterial cells, effectively minimizing interference between elements. system exhibits remarkably low mutual coupling, measuring below −40 dB, with envelope correlation coefficients 0.00010, diversity nearing 10 channel loss capacity 0.11 bit/s/Hz across frequency spectrum under investigation. Experimental evaluations have confirmed these improvements, establishing proposed as robust candidate suitable wide range millimeter-wave communication systems.

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.

The design of wideband multi-port multiple-input multiple-output (MIMO) antennas and their optimization are very important for next-generation smartphones with the increase in massive connectivity. This paper offers design, simulation, measurement, specific absorption rate (SAR) analysis a Pi-shaped ten-element MIMO antenna system use upper mid-band, covering LTE 46 (5.15–5.925 GHz), 47 (5.855–5.925 n102 (5.925–6.425 thus meeting good fractional bandwidth 32.7% maximum peak gain 2.89 dBi. Hence, it is well suited high-isolation (<−10 dB), compactness, (4.7–6.5 GHz) applications suitable current communication needs. overall size proposed 125 mm × 70 mm, planar dielectric material Rogers RT/5880. Designing multiple units entails preservation spatial features alongside reduction mutual coupling adjacent elements by using decoupling structure. Due to high accuracy positioning precise geometric transformations, provides high-performance based on reflection coefficients, radiation patterns, each antenna’s averaged efficiency values (76.12–91.57%).
