[0002] 5G Massive MIMO electronically tunable antennas need to integrate phase shifter modules, RET modules, and calibration network modules on the basis of conventional Massive MIMO antennas. The integration requirements are high, which poses a huge challenge to the realization of reliability and electrical performance.

[0003] The existing 5G Massive MIMO electronically adjustable antenna solution has a complex structure and low integration, which leads to high product size, weight, and high cost. On the other hand, there are multiple 5G commercial frequency bands in different regions of the world. In general, there are two solutions to the existing solutions for the 5G frequency band in the region. One is to make the internal components of the antenna more complicated to achieve broadband characteristics. In this way, the manufacturing process of the antenna will become more complicated and the cost will not be obtained Effective control, the second is to develop different antennas for different frequency bands, so that the number of antenna products will increase, so that the R&D and design costs and operation and maintenance costs of antenna manufacturers will increase relatively
