As the core pillar of future communication and radar technology, terahertz phased array systems have broad prospects in 6G communications, satellite communications and ultra-low latency applications. This paper reviews the main architectures of terahertz phased array systems, including intermediate frequency phase shifting, local oscillator phase shifting, baseband phase shifting and radio frequency phase shifting, and analyzes their advantages, disadvantages and technical challenges in different application scenarios. Special attention is paid to the research progress of terahertz phased array systems based on CMOS technology and terahertz phased array transceivers, covering design breakthroughs from W-band to over 0.5 THz. These emerging technologies provide new design ideas for high-frequency phased array systems, which are expected to play a key role in future ultra-high-speed communications and low-latency applications.References
