摘要

研究了一种测量变压器式平衡器s参数的方法。在网络分析仪的TRL校准中，将两个待测平衡视为误差等效电路。给出了该方法所需的条件，并估计了条件引起的误差。利用TRL法测得的s参数，确定了带平衡轮的偶极子天线的复天线因子(CAF)，并与三天线法测得的结果进行了比较

Measurement of S-parameters of balun and its application to determination of complex antenna factor

A method to measure the S-parameters of a transformer-type balun is investigated. The two baluns to be measured are regarded as error equivalent circuits in the TRL calibration of a network analyzer. The required conditions for this method are shown, and the errors due to the conditions are estimated. The complex antenna factor (CAF) of a dipole antenna with the balun is determined form the S-parameters measured by the TRL method, and compared with the result obtained by the three-antenna method
