摘要
随着5G技术的快速发展,高频天线测试需求的日益剧增,紧缩场作为关键测试设施,其静区性能评估和校准工作变得极为重要.但当前的校准方法难以满足日益发展的需求,以及解决高频测量过程中的相位测量、动态范围、阻抗匹配、电磁兼容性、极化特性和探头耦合等问题.因此,本文根据相位校准算法、动态压缩技术、误差矢量校正、极化分解测试和耦合场分析等,利用连续调频波检测吸波材料缺陷,提出一种新的解决方法.
Abstract
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.
