The invention relates to a large-scale MIMO array antenna and an antenna system. The large-scale MIMO array antenna comprises an antenna unit module. The antenna unit module comprises a plurality of sub-array units, a power division network module and calibration network modules. A plurality of sub-array elements are arranged in an array manner, and the sub-array elements include at least one radiating element, each sub-array element having two first radio frequency ports. The calibration network modules are one-to-one connected with the third radio frequency ports of the power division network module through the fourth radio frequency port, and a plurality of fifth radio frequency ports of the calibration network module are centrally connected with a multi-port radio frequency connector.according to the large-scale MIMO array antenna described above, the radio frequency port are centrally connected to the multi-port radio frequency connector, the multi-port radio frequency connectoris connected with the jumper wire of the radio frequency equipment, the compactness of the structure of the large-scale MIMO array antenna can be improved, the radio frequency port arrangement of theantenna can be optimized, the assembly, disassembly and maintenance of the antenna can be facilitated, and the construction difficulty of the whole wiring project can be simplified.
Description
technical field [0001] The invention relates to the technical field of antennas, in particular to a massive MIMO array antenna and an antenna system. Background technique [0002] With the refined and deep coverage of mobile communication networks, research on the fifth-generation mobile communication technology (5th-generation, 5G) with massive MIMO arrays (ie, large-scale antenna arrays) has been carried out. However, the existing 5G antenna unit is usually built into the radio frequency equipment, that is, the 5G antenna unit is packaged in the radio frequency equipment. This traditional application method is not easy to assemble and disassemble, and it will also bring a lot of inconvenience to the subsequent installation and maintenance. . Contents of the invention [0003] Based on this, it is necessary to overcome the defects of the prior art and provide a massive MIMO array antenna and antenna system, which can facilitate antenna assembly, disassembly and maintenan...
