| 摘 要： | 使用矢量网络分析仪对射频吸波材料低频段吸波性能进行测试的过程中，由于同轴反射计与测试仪器阻抗失配，将引起不希望有的反射。文中主要讨论如何设计同轴反射计的合理高度及阻抗过渡形式，并利用网络分析仪的时域门将装置阻抗失配所引起的反射滤除，使测试结果更为准确。

| Abstract: | In the process of measuring absorber radio-frequency performance with vector network analyzer,the impedance of Vertical Low-frequency Coaxial Reflectometer is mismatched with measurement instrumentation and causes unwanted reflection.In order to filter out reflection by using time-gate of the network analyzer,the modified design of the reasonable height of device and the form of the impedance transition are discussed in this paper. |

| Keywords: | vertical low-frequency coaxial reflectometer RF absorber time-gate |
