Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to an antenna system and an access network device. Background technique [0002] In mobile communication network engineering, base station antennas should be reasonably selected according to actual conditions such as network coverage requirements, traffic distribution, anti-interference requirements, and network service quality. [0003] Currently, analog signals are first power-aggregated through a bridge network before they are emitted by base station antennas. The bridge network is mainly a network device composed of four co-frequency combiners or 4M co-frequency combiners, where M is a positive integer. Specific as Figure 1A As shown, the first electric bridge sub-network includes two same-frequency combiners, and since the same-frequency combiner 2 inputs 2 outputs, the two same-frequency combiners in the first electric bridge sub-net...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that under the structure of the above-mentioned bridge network, only four-input and four-output, eight-input and eight-output schemes can be supported, and schemes such as three-input and three-output, five-input and five-output schemes are not supported.

In practical applications, the coverage of most base stations includes three sectors, and the power sharing between the antenna signals of the sector devices in the three sectors requires a three-input and three-output antenna transmission system, which cannot be satisfied by the above scheme.
