摘要
在使用矢量网络分析仪对射频吸波材料进行测试的过程中,由于矩形同轴装置阻抗不匹配,将引起不希望有的反射。文章主要讨论如何使用网络分析仪的时域门将装置阻抗不匹配所引起的反射滤除,最终获得较满意的测试结果。同时,分析了矩形同轴装置高度对测试的影响,提出了合理的测试装置高度。
In the process of measuring radio frequency absorb material by vector network analyzer, the impedance of rectanglecoaxial measuring device is mismatched and cause redundant reflection. This paper mainly discuss how to use time-gateof the network analyzer and filter reflection caused by mismatched impedance of device. At the same time, analyze theinfluence of the height of rectangle coaxial device on measuring, and put forward reasonable height of device.
