Research of antenna parameter influence on millimeter wave propagation characteristics in vacuum pipeline

The traditional radio wave propagation model is not suitable for vacuum pipeline traffic. Aiming at the maglev train communication in the vacuum pipeline, the radio wave propagation model in the vacuum pipeline is proposed and analyzed. Firstly, the model of the vacuum pipeline is established, the propagation of the direct wave and the reflected wave of the radio wave in the communication process is analyzed, and the composite electric field strength at the receiving antenna is calculated. Then, the model is verified by changing the height of the ground base station, the antenna parameters, and the frequency to analyze the influence of the radio wave propagation process. The propagation process of line wave in vacuum pipelines provides a reference for the application of vacuum pipeline transportation.
