摘　　要：本文以检测电力电缆局部放电的超高频传感器天线为研究对象,在常用的UHF天线中阿基米德螺旋天线具有较宽的工作频带以及优良的低频工作特性,因此本文用ANSYS HFSS设计了一款用于电力电缆UHF传感器的阿基米德螺旋天线。研究了不同外径阿基米德螺旋天线的S11参数,通过改进阿基米德螺旋天线两臂结构对S11参数进行优化,结果表明优化后的阿基米德螺旋天线工作频带较宽、S11参数远低于-10 dB。这为用于电力电缆的UHF传感器天线设计提供了一定的理论依据。This paper takes the UHF sensor antenna as the research object for detecting partial discharge of power cables.Among the commonly used UHF antennas,the Archimedes spiral antenna has a wide operating frequency band and excellent low-frequency operating characteristics.Therefore,this paper uses ANSYS HFSS to design an Archimedes spiral antenna for UHF sensors on power cables.The S11 parameters of Archimedean spiral antennas with different outer diameters are studied.The S11 parameters are optimized by improving the two-arm structure of the Archimedean spiral antenna.The results show that the optimized Archimedean spiral antenna has a wider working frequency band.The S11 parameter is much lower than-10 dB.This provides a certain theoretical basis for the design of UHF sensor antennas used in power cables.
