| Abstract: | 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. |
