W-band refers to a frequency range within the microwave spectrum, specifically between 75 and 110 GHz. It is a high-frequency band that offers high data rates and low latency for wireless communication systems. W-band technology is commonly used in applications such as radar systems, satellite communications, and high-speed wireless networks. Research in the W-band field focuses on developing advanced technologies and devices to optimize communication performance in this frequency range. This includes investigating new antenna designs, signal processing techniques, and modulation schemes to improve transmission efficiency and reliability.
