Dual system independent downward inclination angle adjustment base station electrically-controlled antenna

Abstract

The invention discloses a dual system independent downward inclination angle adjustment base station electrically-controlled antenna, and the antenna comprises a front radiating element and a back feed network. The feed network comprises a single combiner, a power dividing combiner and an independent phase shift part, the independent phase shift part comprises two layers, and the two layers can respectively and independently adjust an electrical downward inclination angle of one system, so that a dual system independent downward inclination angle adjustment function is realized. Each system adopts an independent feed cable network to form a vertical plane directional diagram, so that forming effect of each system can be effectively improved. Upper and lower phase shift modules comprised by the independent phase shift part and a middle power divider can commonly realize a six-way phase shift function, a good vertical plane forming effect can be acquired, feeder connection can be effectively dispersed, so that the assemblability and the index consistency can be greatly improved. The dual system sharing radiating element, independent forming and independent adjusting downward inclination angle base station electrically-controlled antenna scheme saves antenna resources and can effectively improve covering effect of each system.

Description

technical field [0001] The invention relates to the field of mobile communication base station antennas, in particular to a base station electric adjustable antenna suitable for dual-system independent downtilt angle adjustment. Background technique [0002] With the issuance of 4G licenses, base station construction has entered a period of rapid development, and antennas have an increasing impact on network performance and user experience. How to select the most suitable antenna when deploying a 4G network to ensure the best network performance and user experience is an issue that mobile operators are increasingly concerned about. [0003] In the deployment of 4G networks, if operators use traditional antennas, they often encounter the following challenges: 1. It is difficult to achieve the optimal dual-band network performance at the same time; 2. The sky space is tight; 3. It is difficult to build and maintain. 4. Antenna weights are difficult to manage, which may easily...
