Railway train-mounted Beidou high precision integrated antenna

提出铁路车载北斗高精度一体化天线设计方案,解决同类天线重复布设问题,节约列车顶部空间。利用干扰分析及隔离处理、抗多路径干扰等关键技术,研制了原型天线,经过测试,功能和性能均满足设计要求,解决了以往无法使用单一天线同时实现高精度定位和短报文通信的难题,一体化设计能够降低天线布设成本。

In order to solve the problem of repeated deployment of similar antennas and save the space on the top of the train, this paper proposed a railway train-mounted Beidou high precision integrated antenna design scheme. Using the key technologies such as interference analysis, isolation processing, and anti-multipath interference, the prototype antenna has been developed. The test shows that the function and performance meet the design requirements. The integrated antenna can solve the problem of high precision positioning and short message communication at the same time, and reduce antenna deployment costs.
