This workshop is designed to provide participants with an overview of the latest developments in RF, millimetre-wave (mm-Wave), and terahertz (THz) antenna technologies and their emerging applications. The workshop will bring together academicians, researchers, industry professionals, and students to explore recent advancements in high-frequency antenna design, electromagnetic simulation, fabrication, measurement, and system-level applications. The sessions will focus on the role of advanced antennas in modern defence systems, satellite and space communication, radar and sensing, and next-generation 5G/6G wireless communication systems. Particular emphasis will be given to practical design challenges and emerging research opportunities in mm-Wave and THz frequency bands.
