This article explains the layout and examination of two-portprinted radiator with a metasurface (MS) absorber wall in betweenthe port and a suspended MS over the designed radiator. The unique characteristics of designed printed multi-inputmulti-output(MIMO) radiator are as follows: (i) Absorbing wall in between the port advances the separation level among the closely spacedantennas by 25 dB and (ii) suspended MS made up with double negative metamaterial unit cell, which adds two importantfeatures, that is, high gain (up to 8.0 dBi) and converts the linear wave into the circularly polarized waves (5.31–5.65 GHz) in betweenworking frequency range. Experimental outcomes have decent promise with optimized simulated findings. The plannedaerial works effectively in between 5.2 and 5.95 GHz with above 25 dB separation. Decent assessment of MIMO parameter andstable radiation features confirms its applicability for sub-6.0GHz-based5G communication system.
