摘　　要：用扫频仪测量天线的输入阻抗时，在同轴传输线与天线间应按平衡—不平衡变换器。针对圆环天线的输入阻抗为复阻抗，提出了一种新的四分之一波长平衡一不平衡变换器，得到了实验结果，并进行了讨论。When using frequency sweep meter to measure the input impedance of antenna, the balanced- unbalanced transformer must be connected between coaxial transmission line and antenna. As input impedance of circular loop antenna is complex impedance, a new one quarter of wavelength balanced-unbalanced transformer is presented for this measurement, the experiment result are got and some discussions are also given.
