摘要

为检测气体绝缘开关设备（GIS）局部放电的超高频（UHF）信号

基于分形技术设计了一种超宽带小型天线。对天线的几何参数进行了优化仿真。该天线的回波损耗（S11）小于10 dB带宽为0.5

.5 GHz（相对带宽为100%）

在频带内方向性良好

能够实现全向辐射;天线具有较高增益

在0.5

GHz频带内方向图主瓣增益为2

dB;天线尺寸较小

实际尺寸为200、160、1.6 mm。搭建了模拟局部放电的实验平台

对研制的天线进行测试

可用于GIS现场局部放电检测。

Abstract

An ultra-wideband（UWB） compact tree-shape antenna

which integrates the fractal technology

was designed for detecting the ultra-high frequency（UHF） signals generated from gas insulated switchgear（GIS） partial discharge（PD）.The geometrical parameters of the antenna were optimized through computer simulation.The fractal antenna offers the return loss（S11） less than-10 dB and the bandwidth in the range of 0.5 to 1.5 GHz（relative bandwidth is 100%）

and it has good great directivity and omnidirectional radiation feature.Besides

the antenna achieves a high gain

e.g.

the main lobe gain is about 2

dB in the range of 0.5

GHz

and it has a compact size of 20

160

1.6 mm.The antenna was tested o

n a discharge simulation platform in laboratory.The results show that the UHF PD monitoring system based on ultra-wideband fractal tree-shape antenna has strong anti-interference ability and can be applied to on-line PD monitoring applications.
