Project Operator National Taiwan University
Project Host 周錫增
Summary 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
