Abstract

Antennas for modern wireless terahertz (THz) systems must be able to enable very fast data transmission, widely span a wide range of frequencies, and be compact enough to integrate with renewable energy sources. A miniaturized and improved quad-band multiple-input multiple-output (MIMO) terahertz antenna is introduced in this study. The antenna makes use of a split ring resonator (SRR) construction. With a broad cumulative bandwidth of 0.75 THz to 11.5 THz, the suggested antenna performs efficiently over four frequency bands: 2.0-2.75 THz, 3.45-4.75 THz, 5.15-7.7 THz, and 8.0-19.5 THz. The corresponding peak gains are 2.45 dBi at 2.45 THz, 6.8 dBi at 3.7 THz, 8.6 dBi at 6.3 THz, 4.1 dBi at 14.75 THz, and 8 dBi at 18.75 THz. Sustainable operation is promoted and self-powered terahertz communication systems are made possible through an integrated solar energy harvesting layer into the antenna design. These systems are suited for remote or low-maintenance applications. The proposed antenna is ideal for energy-autonomous IoT devices, terahertz sensing, and next-gen green wireless communication due to its solar power, quad-band MIMO, and metamaterial-influenced SRR design.
