A Sensing-Based Over-the-Air Phased Array Antennas Phase Calibration Method With Greedy Algorithm

Phase errors of phased array antennas can cause gain degradation that necessitates calibration to compensate this effect. Over-the-air (OTA) calibration methods are promising for avoiding interruption of communication applications for specific calibration conditions. However, typical calibration methods have the assumption that precise knowledge about calibration should be exchanged, such as relat...
