AI Technical Summary
Technical Problem
Traditional base station array antennas have a large profile height, which is not conducive to miniaturization. Furthermore, electromagnetic interference can easily occur between the feed network and the radiating element, affecting antenna performance.
Method used
The first power supply network and the first radiation unit are both set on the same surface of the reflector, and the phase shifting device is set at an angle to the reflector to reduce the projected area of the phase shifting device on the reflector. The phase shifting medium is protected by the housing to reduce electromagnetic interference.
Benefits of technology
This has enabled the miniaturization of antennas, reduced electromagnetic interference, and improved antenna performance and efficiency.
