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 ...
