摘　　要：设计了一种可抑制通信频带干扰的局部放电超高频检测用新型对数周期天线。利用ANSYS HFSS软件仿真分析了传统对数周期天线,在此基础上设计了可抑制通信干扰(0.80~1.00 GHz)的超高频对数周期天线,并通过理论分析和实验验证探讨了所设计天线的性能。结果表明:通过去除对数周期天线中通信频段相对应的振子,并微调附近振子相关参数,可以提高该频段的驻波比,抑制通信干扰信号;去除不同振子组合是实现个性化“操控”对数周期天线驻波比的有效方法;对数周期天线振子的删减和参数调整不影响天线的方向性。A new log-periodic antenna for partial discharge UHF detection that could suppress the interference of communication frequency bands was designed.The traditional log-periodic antenna was simulated and analyzed by ANSYS HFSS software,and on this basis,an ultra-high frequency log-periodic antenna that could suppress communication interference(0.80~1.00 GHz)was designed,and the performance of the designed antenna was discussed through theoretical analysis and experimental verification.The results show that by removing the oscillator corresponding to the communication frequency band in the logarithmic periodic antenna and fine-tuning the relevant parameters of the nearby oscillator,the Voltage Standing Wave Ratio(VSWR)of this frequency band can be improved and the communication interference signal can be suppressed;removing different oscillator combinations is an effective way to achieve personalized“manipulation”of logarithmic periodic antenna VSWR;the deletion and parameter adjustment of the logarithmic periodic antenna oscillator do not affect the radiation pattern of the antenna.
