Abstract

Embodiments of the invention relate to the communication technology field and provide a base station antenna and a base station antenna feed network. The base station antenna comprises a transceiver array, a first-level vector synthesis network, a two-level phase shift array, a second-level vector synthesis network and an antenna unit array. By means of the second-level vector synthesis network, the base station antenna makes smoother the phase difference of multiple vector signals that are transmitted to an antenna unit, thereby increasing the range of adjusting a downward inclination angle of the antenna on the premise that the number of transceivers is as small as possible.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a base station antenna and a base station antenna feeding network. Background technique [0002] As an important part of the mobile communication network, the base station antenna carries the dual functions of electromagnetic wave transmission and reception. Its performance directly determines the quality of the mobile communication network, and the downtilt angle of the antenna is an important factor affecting the performance of the base station antenna. [0003] In an active base station antenna system, multiple antenna units can be fed through two or more TRXs (Transceivers) and a vector synthesis feed network to form a radiation beam with a certain downtilt angle. The inventors found that when the number of TRXs is small, for example, when there are only two TRXs, the adjustable range of the downtilt angle of the base station antenna is small, which is difficul...
