| 摘 要： | 为测量金属结构件表面的传导电流,设计了耦合面为平面结构的电流探头.根据传输线理论设计并制作了平行板传输线校准装置,以获取探头的传输阻抗曲线.使用矢量网络分析仪测量探头放入前后装置输入端的电压驻波比均小于1.3.建立了电流探头信号检测的等效电路模型,并由此推导出传输阻抗的计算公式,测试值曲线与计算式得出的趋势吻合.从装置...

| Abstract: | A surface current probe with flat structure of contacting surface was designed and manufactured,which can be used to measure conductive current that flows on metal structure surface.In order to obtain the transfer impedance values of the probe,a parallel plate transmission line device was designed based on the transmission line theory,and then constructed.The measured VSWR(voltage standing wave ratio) with or without probe placed in the line by vector network analyzer is less than 1.3.An equivalent circuit ... |
