This paper reviews the state-of-the-art in millimeter wave and terahertz technologies, and summarizes several important future directions, mainly based on worldwide development trends. In millimeter-wave (MMW) technology, this paper mainly focuses on the introduction of the MMW chip in recent years, with details given of typical application areas of MMW systems, such as MMW communication, MMW imaging, and MMW radar. Compared to the MMW frequency bands, exploration of the terahertz (THz) spectrum is still at an early stage. Thus, emphasis is placed on several key THz technologies, including THz source, THz transmission, THz detection, THz devices. Several promising THz application areas such as astronomy, nondestructive testing, life sciences, safety, and high-speed communication are also discussed.
