Description

Technical Field

[0001] The present invention relates to the technical field of phased arrays, and more particularly to a phased array antenna and system based on POE power supply control. Background Art

[0002] At present, phased array, as the most advanced antenna technology, has been very maturely applied in the military field. Its unique phase control capability makes it the representative of antennas. The unique phase-controlled electronic scanning array of the RIS phased array communication system enables the signal to have flexible functions close to the user, which can meet the characteristics of various deep mountains, water, high altitude, large temperature difference, high salt corrosion, and uninhabited areas, and carry out point-to-point, point-to-multipoint, high speed, large angle, large swing, bumpy and other high-mobility disaster prevention communication needs.

[0003] However, traditional phased array power supply uses high-power DC power supply, which consumes too much power. In addition, it also requires an industrial communication interface for control, which has too many interfaces and is not easy to integrate.
