摘要
为达到某移动通信系统对漏泄同轴电缆主要电气指标的要求,设计一种U形漏泄同轴电缆,以满足工程应用。阐述了漏泄同轴电缆耦合损耗和传输衰减两个重要电气指标,以U形漏泄同轴电缆实例,利用三维电磁仿真软件HFSS仿真分析900 MHz工作频率下节距及槽孔尺寸的变化对耦合损耗、传输衰减的影响,仿真结果与实测结果吻合良好。结果表明U形漏泄同轴电缆节距越小,漏泄同轴电缆耦合损耗越小。
To reach the main electrical indicators needs of leaky coaxial cables for a mobile communication system,a U-shaped leaky coaxial cable is designed,satisfying the engineering application. The coupling loss and transmission loss are elaborated. At the operating frequency 900 MHz,the U-shaped leaky coaxial cable modeling is simulated in the 3D electromagnetic simulation software HFSS,and the effect of the variation of interval and slot size on coupling loss and transmission attenuation are analyzed. The simulation results are in good agreement with experimental results. It shows that the smaller the sub slot interval is,the smaller coupling loss is.
