Advances in mm-Wave and THz Circuit Design for Future Communications

mm-Wave and THz circuit technologies are advancing rapidly to meet the growing demand for high-speed, high-capacity, and long-distance wireless communication. Two major directions are driving this progress: the use of higher frequencies such as sub-THz to achieve ultra-fast data transmission even over longer distances, and the deployment of massive MIMO using mm-wave to dramatically increase communication capacity. This talk will first introduce a theoretical outlook on future trends in mm-wave wireless communication for next-generation communication systems including 5G, Beyond-5G, 6G, and satellite applications. Following this perspective, the talk will highlight recent developments in ultra-fast sub-THz radios, focusing on their potential to support higher data-rates and extended coverage. The presentation will then explore mm-wave massive MIMO technologies, with a particular emphasis on the emerging role of discrete-time operation in mm-wave circuit design. This approach enables scalable phased array architectures realizing TD-MIMO (Time Division MIMO), supporting the development of energy-efficient, high-capacity wireless systems with enhanced flexibility and integration potential. The talk aims to provide insights into the evolving landscape of mm-wave and THz circuit design and its impact on future wireless communication.
