Dual-Band Loop-Resonator-Based MIMO Antenna Architecture for 6G and Terahertz Wireless Communication Systems

This study presents a 4-element MIMO antenna array designed for THz and 6G communications. The antenna features a straightforward design, utilizing low-profile loop elements fed by microstrip lines, positioned on different sides of a compact board with overall dimensions of 0.16×0.16 mm 2 substrate. The proposed MIMO antenna demonstrates dual-band functionality, operating effectively at 1.5 THz and 2.2 THz. The array shows strong potential in terms of key performance metrics, including S-parameters, radiation patterns, and gain/efficiency levels, making it a promising candidate for future wireless networks.
