Dual-Band MIMO Antenna with S-Shaped Monopole Resonators for 2.5/3.5 THz 6G Communications

This study presents a 4-element MIMO antenna array designed for THz and 6G communications. The antenna features a straightforward design, utilizing low-profile S-shaped monopole elements fed by microstrip lines, positioned on different sides of a compact board with overall dimensions of 13 x 13 μm, The proposed MIMO antenna demonstrates dual-band functionality, operating effectively at 2.5 THz and 3.5 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 networks.
