Base station antenna and its antenna array module

Abstract

The invention discloses an antenna array module. More than two antenna units are arranged on a surface, which two power division circuits are arranged, of a feeding network circuit board, a filter isarranged on a surface, which two coupling circuits are arranged, of the feeding network circuit board, each power division circuit is provided with an input end and a plurality of output ends, the plurality of output ends of one of the power division circuits is used for performing polarization feeding on one of the antenna units at -45 degrees, the plurality of output ends of the other power division circuit are used for performing polarization feeding on one of the antenna units at +45 degrees, each coupling circuit is provided with a radio frequency input end and an output end, the output end of each coupling circuit is electrically connected with the input end of one of power division circuits, the filter is at least provided with two output ends, and the two output ends of the filterare electrically connected with the radio frequency input end of one of the coupling circuits. The invention also discloses a base station antenna. Integration and modularization are achieved, the expansibility is improved, an installation structure and a connection structure are simple, the antenna array module is easy to debug and maintain subsequently, and the manufacturing cost and the application cost are reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a base station antenna and an antenna array module thereof. Background technique [0002] The large-scale antenna array system (Massive MIMO) is the core transmission technology of 5G in the future, and it is also an important link to solve the development of communication traffic in depth and breadth. At present, under the background of major operators launching commercial 5G networks in the next few years, equipment manufacturers and related antenna suppliers are intensively carrying out relevant pre-research work. [0003] However, in the existing technology, a large number of antenna units and all related radio frequency components such as filters and calibration network adapter boards are all installed and fixed in one body. The installation structure and connection structure are complicated, and subsequent debugging and maintenance are not easy, resulting in ...
