Investigation of the Current Status and Proposed Solutions for Compact Range Calibration
With the rapid development of 5 G technology,the demand for high frequency antenna testing is increas-ing day by day.As a key test facility,the static zone performance evaluation and calibration work of the compact field become extremely important.However,current calibration methods are difficult to meet the growing needs and solve the problems of phase measurement,dynamic range,impedance matching,electromagnetic compatibility,polar-ization characteristics and probe coupling during high-frequency measurement.Therefore,according to phase cali-bration algorithm,dynamic compression technique,error vector correction,polarization decomposition test and cou-pled field analysis,a new method is proposed to detect the defects of absorbing materials by using continuous fre-quency modulation waves.
