Two‐Port Circularly Polarized Printed Radiator With High Gain and Isolation Features for Sub‐6 GHz 5G Applications
Year: 2025
Type: article
Abstract: ABSTRACT This article explains the layout and examination of two‐port printed radiator with a metasurface (MS) absorber wall in between the port and a suspended MS over the designed radiator. The unique characteristics of designed printed multi‐input multi‐output (MIMO) radiator are as follows: (i) Absorbing wall in between the port advances the separation level among the closely spaced antennas by 25 dB and (ii) suspended MS made up with double negative metamaterial unit cell, which adds two important features, 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 between working frequency range. Experimental outcomes have decent promise with optimized simulated findings. The planned aerial works effectively in between 5.2 and 5.95 GHz with above 25 dB separation. Decent assessment of MIMO parameter and stable radiation features confirms its applicability for sub‐6.0 GHz‐based 5G communication system.
