Problems solved by technology
[0002] The existing antennas mainly have the problems of high integration and high material cost, mainly related to: 1. The power distribution board and the calibration board are highly integrated, which is inconvenient for manufacturing and quality control; the power distribution boards of the prior art adopt full-page design , that is, all radiating units are welded on the same power splitter board, but it is inconvenient to carry out automatic welding design, and it is not convenient to carry out inspection, maintenance or replacement separately, and there is a risk of scrapping the entire antenna due to the failure of a certain module
Second, the material cost of the power distribution board and the calibration board is high; the existing technology integrates the power distribution board and the calibration board, the processing is complicated, and because of the intricate wiring inside, it is difficult to achieve the optimal size of the PCB board, which affects the material cost

The invention belongs to the technical field of communication, and relates to a large-scale MIMO antenna comprising a reflection plate, a calibration network arranged on one side of the reflection plate and N*M antenna subarrays arranged on the side of the reflection plate away from the calibration network, wherein N is a positive integer greater than or equal to 1 and M is a positive integer greater than or equal to 2. The antenna subarrays comprises a power dividing plate and a radiation unit arranged on the power dividing plate. The power dividing plate has a microstrip line structure. Thecalibration network has a microstrip line structure or a strip-line structure. The thickness of the reflection plate is 1.5mm-3mm. The antenna subarrays are connected with the calibration network through a probe. The antenna subarrays and the calibration network are respectively connected with the reflection plate through metal screws, and at least one metal screw is arranged around the probe. Theantenna subarrays, the calibration network and the reflection plate are modularized so that detection, maintenance or replacement of a single module can be facilitated; besides, at least one metal screw is directly grounded around the feeding probe so that the antenna signal transmission is good.
