Microwave bands refer to specific ranges of frequencies within the microwave spectrum, which is part of the electromagnetic spectrum. These bands are typically categorized by their wavelengths, ranging from 1 millimeter to 1 meter. Common microwave bands include the L-band, S-band, C-band, X-band, Ku-band, and Ka-band, each serving different applications in communication, radar, and satellite technologies. These bands are crucial for various technologies, including cellular networks, Wi-Fi, and satellite communications. Each band has unique characteristics that make it suitable for specific uses, such as data transmission rates and range. Understanding these bands helps in optimizing the performance of microwave-based systems.
