Embodiment Construction
[0029] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0030] See figure 1 In this embodiment, a single-column antenna electric adjustment system is provided. The system includes: a single array of M arrays 101, a sub-array-level N-drive M multi-band feeder module 102, a combiner group 103 and K electric adjustment modules , Where N, M, and K are all positive integers, and N is less than M, and K is the number of communication systems sharing a site address, and each communication system corresponds to an ESC module;
[0031] Each of the ESC modules is connected to the corresponding input ports of the N combiners in the combiner group, and the output ports of the combiner group are connected to the sub-array level N-drive M multi-band feed module The input ports are connected, and the output ports ...

The invention discloses an electrically regulated antenna system and an electric regulation method, belonging to the technical field of communication. The electrically regulated antenna system comprises single-row M arrays, subarray-level N driven M multi-band feeding module, a combiner group and K electric regulation modules, wherein N, M and K are all positive integers, N is less than M, each communication system corresponds to one electric regulation module; N output ports of each electric regulation module are respectively connected with corresponding input ports of N combiners in the combiner group, the output ports of the combiner group are connected with the input ports of the subarray-level N driven M multi-band feeding module, and the output ports of the subarray-level N driven M multi-band feeding module are connected with the input ports of the single-row M arrays. According to the electrically regulated antenna system, for M arrays in each row, unification of the antennae of multiple systems can be realized just by N combiners, and independent electric regulation on the downward inclination angle of each system is realized, thus the electrically regulated antenna system is high in realizability and low in cost.
Description
Technical field [0001] The present invention relates to the field of communication technology, and in particular to an electric adjustment antenna system and an electric adjustment method. Background technique [0002] With the rapid development of mobile communication in the world, mobile communication is increasingly providing convenience and speed for people's work and life. The mobile communication system has developed to the current third-generation mobile communication systems such as WCDMA (Wideband Code Division Multiple Access) and CDMA2000, and is moving towards the fourth generation represented by LTE (Long Term Evolution). Modern communication system development. However, due to the shortage of site resources, the narrow site space, and the advocacy of green base stations, in the future, base stations will face the situation of multiple systems sharing sites, so it becomes inevitable for multiple systems to use the same antenna. [0003] On the premise that multiple s...
