| 摘 要： | 为了有效完成铁路沿线的安全监测,基于北斗警犬状态远程监测系统应运而生,目前存在着监测系统中天线受环境影响大、接收性能差等问题,针对上述问题设计了一种平面微带天线。本文以单支节调配器为主线,以应用角度出发,分别对其平面及馈线弯折等情况进行了仿真分析,克服铁路特殊环境北斗天线安装困难、频带窄易受干扰等缺点。采用ANSOFT HFSS软件进行天线性能仿真,仿真结果表明,设计的北斗天线有效中心频率为1571MHz,电压驻波比小于1.5,符合警犬状态远程监测的实际应用要求。

| Abstract: | In order to secure effective monitoring along the railway line, based Compass dogs Remote Monitoring system came into being, there exists a planar microstrip antenna monitoring system by the large environmental impact, poor reception performance, designed to address the problem antenna. In this paper, single stub tuner main line to the application point of view, were simulated and analyzed feeder plane bending, etc., to overcome the special circumstances of railways Beidou antenna installation difficulties, shortcomings narrow band susceptible to interference. ANSOFT HFSS software using the antenna performance simulation results show that the design of the antenna Compass effective center frequency of 1571MHz, VSWR less than 1.5, in line with the requirements of the application status of the remote monitoring of police dogs. |
