摘要:

為了有效完成鐵路沿線(xiàn)的安全監測,基于北斗警犬狀態(tài)遠程監測系統應運而生,目前存在著(zhù)監測系統中天線(xiàn)受環(huán)境影響大、接收性能差等問(wèn)題,針對上述問(wèn)題設計了一種平面微帶天線(xiàn)。本文以單支節調配器為主線(xiàn),以應用角度出發(fā),分別對其平面及饋線(xiàn)彎折等情況進(jìn)行了仿真分析,克服鐵路特殊環(huán)境北斗天線(xiàn)安裝困難、頻帶窄易受干擾等缺點(diǎn)。采用ANSOFT HFSS軟件進(jìn)行天線(xiàn)性能仿真,仿真結果表明,設計的北斗天線(xiàn)有效中心頻率為1571MHz,電壓駐波比小于1.5,符合警犬狀態(tài)遠程監測的實(shí)際應用要求。

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.
