AI Technical Summary

Technical Problem

Existing base station antennas cannot achieve independent and continuous reconfigurability of horizontal beamwidth, horizontal beam pointing, and vertical beam pointing under the premise of simple structure and controllable cost, making it difficult to meet the diverse coverage requirements of 5G-Advanced and future mobile communication networks.

Method used

An array antenna design including a radiating element array, a horizontal feed network, and a vertical phase-shifting network is adopted. The horizontal beamwidth and the horizontal and vertical beam pointing can be independently and flexibly reconfigured by electric adjustment. The horizontal and vertical beam pointing can be adjusted by the horizontal and vertical wave adjustment drive mechanisms, respectively, to achieve independent, continuous, and reconfigurable three-dimensional beamwidth and vertical beam pointing.

Benefits of technology

It enables independent and continuous reconfigurability of the array antenna in terms of horizontal beamwidth, horizontal beam pointing and vertical beam pointing, which improves the freedom of network planning and optimization. It has a compact structure, simplified control and is easy to operate, and is suitable for the widespread use of passive antennas.
