Abstract

Abstract-In this paper, a new type of microstrip antenna is designed using coplanar waveguide feeding as the feeding method of the antenna, which is used for partial discharge detection in high-voltage substation equipment. The basic structural parameters of the antenna are calculated by theoretical formulas, and the original model of the antenna is designed. Model the antenna in High Frequency Structure Simulator (HFSS). The effects of main structural parameters such as the length of the rectangular radiating patch, the width of the conduction band and the width of the ground plane on the performance of the antenna are studied, and these parameters are optimized. The results show that in the working frequency band of $500 \mathrm{MHz} \sim 1120 \mathrm{MHz}$, the value of input return loss S11 is less than -10, and the value of standing wave ratio is less than 2. In addition, the antenna has good resonance characteristics in the entire working frequency band, and is capable of meeting the needs of the radio frequency detection method.

一种基于共面波导馈电的局部放电检测天线设计方法

摘要:本文设计了一种采用共面波导馈电作为馈电方式的新型微带天线，用于高压变电设备的局部放电检测。利用理论公式计算了天线的基本结构参数，并设计了天线的原始模型。利用高频结构模拟器(HFSS)对天线进行建模。研究了矩形辐射片长度、导带宽度和接地面宽度等主要结构参数对天线性能的影响，并对这些参数进行了优化。结果表明，在$500 \mathrm{MHz} \sim $ 1120 \mathrm{MHz}$工作频段，输入回波损耗S11值小于-10，驻波比值小于2。此外，该天线在整个工作频带内具有良好的谐振特性，能够满足射频检测方法的需要。
