The microwave communication based on the omnidirectional radiation has been studied for long time, and now we have started using the millimeter-wave directional wireless communication based on the beamforming technique. In this presentation, millimeter-wave and terahertz phased-array transceivers by CMOS technology will be introduced, which are designed for 5G and 6G communication. The talk concludes with a discussion on future directions of wireless communication.
