无需短路活塞相位信息的波导同轴转换器校准方法

A Coaxial-to-waveguide Adaptor Calibration Method using an Adjustable Shorter with Unspecified Phases

针对采用矢量网络分析仪测量波导设备反射系数的问题，推导出一种采用匹配负载和短路活塞校准波导同轴转换器的方法。校准时只需要确定一个相位参考面，不需要记录短路活塞的位置信息。该方法消除了读刻度带来的误差，实施方便。在X波段通过一组实测数据验证了该方法的有效性。

A technique is described to remove the coaxial-to-waveguide adaptor errors when the reflection coefficient of waveguide device is measured by vector network analyzer. This technique utilizes a matched load and an adjustable shorter with several unspecified phases. And one of the shorted planes is used as reference plane. It is shown that the technique is resistant to the error of the adjustable shorter position and is easy to implement. The efficiency of this technique is verified by measurement data in X band.
