This comprehensive study introduces a meticulously designed and characterized
terahertz (THz) multiple-input multiple-output (MIMO) antenna engineered to
operate within the 0.4 THz to 1.6 THz frequency range. The antenna’s construction
includes a copper patch and ground plane integrated into a polyimide
substrate, ensuring exceptional durability and robust performance. Significantly,
the antenna reveals four distinct resonance frequencies at 0.46 THz, 0.9 THz,
1.31 THz, and 1.44 THz each accompanied by bandwidths of 0.005 THz, 0.17
THz, and 0.34 THz, respectively. Moreover, the antenna delivers notable gains
of 8.52 dB, 11.54 dB, and 13.25 dB at these frequencies, coupled with substantial
efficiencies of 88.32%, 92.02%, and 89.89%, respectively. Additionally, the
antenna showcases exceptional isolation of 26 dB, a low envelope correlation
coefficient (ECC) of 0.003, and a diversity gain (DG) of 9.98. These remarkable
attributes underscore the antenna’s aptness for high-performance THz applications,
offering substantial advantages in terms of gain, efficiency, and isolation
for next-generation wireless communication systems.
