The sixth-generation (6G) standard for wireless communications is currently under research and development from both industry and academia. It is anticipated that 6G wireless networks will use higher frequencies than 5G networks, which will enable much higher data rates to be achieved with much lower latency levels. Millimetre-wave and terahertz communications, ultra-massive multiple-input multiple-output (MIMO), and reconfigurable intelligent surfaces (RISs) have been envisioned as enabling technologies for 6G wireless communications. On the physical layer, antennas are critical components for 6G communications systems. It is known that transmission at such high frequencies incurs very high propagation losses, which significantly limits communications distances. To overcome this, it is required that either the antenna is designed to have a high gain or the use of an array antenna is necessary. Moreover, 6G antennas and arrays should be cost-effective; otherwise, it would limit its deployment. Recently, there have been many reported research works on 6G antenna systems and associated technologies. The objective of this special session is to present the latest development and technical challenges in mm-wave/THz antennas and RISs for 6G applications. This special session is dedicated to bringing together researchers from relevant research areas of the 6G antennas to share their new ideas, latest accomplishments, research findings, open research problems and technical challenges within the research community.
