With the escalating demand for high data rates, the currently utilized electromagnetic (EM) spectrum faces congestion, limiting data movement and creating bottlenecks in communications. To address these challenges, communication systems are expanding into higher frequencies, where the sub-terahertz-band (100 GHz to 300 GHz) offers large, untapped bandwidth and significant potential for high data-rate applications. However, operating within the band presents unique challenges due to the absence of sufficiently efficient RF electronics that meet the stringent size, weight, and power (SWaP) constraints required for compact systems. This project proposes to investigate the design and integration of sub-terahertz antennas and arrays operating in the G-band, focusing on creating compact, high-efficiency phased arrays and massive MIMO systems. The study will incorporate silicon-based RF integrated circuits (ICs) and III-V compound semiconductor MMICs, aiming to achieve compact, high-performance, cost-effective sub-terahertz antennas with 3D heterogeneous integration for future data-intensive applications.
