Abstract

The invention relates to the technical field of mobile communication, and discloses a Massive MIMO antenna, which comprises a power division network module, a coupling calibration network module and aplurality of radiation sub-arrays, and is characterized in that the power division network module comprises a plurality of first power dividers, and the plurality of first power dividers are connected with the plurality of radiation sub-arrays in a one-to-one correspondence manner; the coupling calibration network module comprises a PCB, and a coupling calibration network formed on the PCB comprises a calibration port, a plurality of main signal channels and a plurality of coupling signal channels; the output ends of the main signal channels are connected with the plurality of first power dividers in a one-to-one correspondence manner; a plurality of filters and a plurality of radio frequency connectors are arranged on the PCB; and the input ends of the plurality of main signal channels are connected with the output ends of the plurality of filters in a one-to-one correspondence manner, and the output ends of the plurality of radio frequency connectors are connected with the input ends of the plurality of filters in a one-to-one correspondence manner. According to the Massive MIMO antenna, miniaturization and light weight of a 5G base station antenna system are realized, and massproduction of 5G equipment is facilitated.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a Massive MIMO antenna. Background technique [0002] With the continuous development of my country's mobile communication technology and the rapid growth of user data traffic, the fourth-generation mobile communication system will soon be unable to meet the needs of users for such a large flow of data. The fifth-generation mobile communication system (5G) has now entered the nationwide Formal commercial stage. Massive MIMO antenna technology has become one of the key technologies for the development of 5G wireless communications. [0003] The front end of the 5G base station antenna system integrates the antenna and the RRU (Radio Remote Unit) module into an AAU (Active Antenna Unit) module. The current large-scale array antenna is at the forefront of the wireless communication system. It mainly uses beamforming to transmit and receive signals. It does not have the...
