[0002] There are four types of antennas in microwave ground equipment, including phased array electronic scanning antennas, data antennas that radiate data words and function identification codes, indication antennas outside the coverage area of ​​scanning signals, and field monitoring antennas. Scanning antennas are divided into azimuth scanning antennas and elevation scanning antennas, providing basic angle guidance information. Both antennas are one-dimensional phased array antennas, consisting of power dividers, phase shifters, and radiation arrays, and are controlled by antenna control boards and bus driver boards. When the scanning antenna fails, it will cause no radiation of scanning information or deviation in angle guidance.
