Compact metamaterial-inspired high isolation triple-band dual-polarised MIMO antenna for 3G-6G applications
Abstract
This paper presents a high-performance, triangular split-ring resonator (TSRR) metamaterial-inspired MIMO antenna with triple-band and dual-polarisation, designed for modern wireless applications, including 3 G, 5 G, and 6 G. The antenna operates in three distinct frequency bands: 1950–2100 MHz, 3.2–4.3 GHz, and 8.0–8.3 GHz, covering 3 G, 5 G (sub-6 GHz), and beyond 5 G (potential 6 G bands). The design evolves systematically from a single TSRR-based antenna element to two, three, and four-element MIMO configurations, effectively addressing the challenge of mutual coupling. A rectangular split-ring structure between the antennas improves isolation by up to −20 dB between the elements. Measurement results show excellent MIMO performance, with input reflection coefficients (S11, S22, S33 and S44)
