Active phased arrays of antennas suffer from fabrication discrepancy at mmW frequencies for 5G/B5G. To accelerate the piece-by-piece calibration procedure, a bottleneck to cause high fabrication cost, a highly efficient electronic-scan based technique is developed. By avoiding the time-consuming mechanical probing, the developed technique is particularly applicable to production line operation to 

This technology utilizes active RF devices to calibrate the array antenna beams, which breaks through traditional iterative mechanical architecture scanning. This electronic-scan based technology can achieve unidirectional beam correction, implement a space reduction of 70,reduce the calibration time from "hours" to "seconds" Level (less than 1 of conventional mechanical

The proposed technique can be applied in various scenarios at mmW frequencies. It may simplify antenna system architecture for low power consumption at R&D stage,reduce development efforts for various RF components. At production stage, it can be applied to production lines for space-saving, cost reductiongood yield rate enhancement. Combining with existing production automation flow usi
