Description

technical field [0001] The invention belongs to the technical field of base station antennas, and in particular relates to a two-low and three-high miniaturized multi-port base station antenna. Background technique [0002] In recent years, with the increase of mobile communication network standards, in order to save site and antenna resources, reduce the difficulty of property coordination, and reduce investment costs, multi-frequency array antennas with co-site and co-location have become the first choice for network construction. Moreover, in existing wireless communication systems, MIMO (Multiple-Input Multiple-Output) antenna technology is an important key technology to improve the quality and efficiency of mobile communication. MIMO technology can make full use of space resources and realize Multi-transmission and multi-reception can greatly increase the system channel capacity, improve channel reliability, and reduce the bit error rate without increasing spectrum reso...
