摘要

For the problem that the traditional method studying leaky coaxial cable radiation characteristics is complex,a simple and easy to implement electromagnetic simulation software HFSS was used for simulation analysis of leaky coaxial cable radiation characteristics.According to leaky coaxial cable single-mode radiation theory,radiation type leaky coaxial cables of different outer conductor gap spacing were designed,distribution of the space radiation field and the internal electric field of the various structures of leaky coaxial cables were obtained from simulation,the analysis results had an important significance for extension of the single-mode band.%针对传统方法研究泄漏电缆辐射特性繁杂的问题,采用简单易于实现的HFSS电磁仿真软件对泄漏同轴电缆辐射特性进行仿真分析.根据泄漏电缆单模辐射理论,建立了不同外导体缝隙间距的辐射型泄漏电缆,仿真得到了各种结构的泄漏电缆内部电场和空间辐射场的分布情况,分析结果对单模频带的扩展有重要意义.
