Title:
MASSIVE MIMO ANTENNA
Document Type and Number:
WIPO Patent Application WO/2021/139205
Kind Code:
A1
Abstract:
The present invention relates to the technical field of mobile communications, and provides a Massive MIMO antenna, comprising a power division network module, a coupling calibration network module, and a plurality of radiation sub-arrays. The power division network module comprises a plurality of first power dividers connected to the plurality of radiation sub-arrays in a one-to-one correspondence manner. The coupling calibration network module comprises a PCB board, and a coupling calibration network formed on the PCB board comprises a calibration port, a plurality of main signal channels, and a plurality of coupling signal channels. Output ends of the main signal channels are connected to 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 board. Input ends of the plurality of main signal channels are connected to output ends of the plurality of filters in a one-to-one correspondence manner, and output ends of the plurality of radio-frequency connectors are connected to 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 mass production of 5G equipment is facilitated.
