Research and Simulation of Train Communication Antenna Model

Due to factors such as train vibration and installation position errors, the onboard antenna of the train communication system in practical applications can cause slight deviation from the random angle position of the onboard antenna, seriously affecting communication performance. In this paper, a physical model of the maglev train onboard antenna is established to address this phenomenon. Based on the model, its transmission performance is analyzed and an improvement plan is proposed, Finally, the improved model was simulated and validated using finite element analysis software ANSYS, and an improved vehicle antenna was made based on the simulation results, effectively improving communication performance.
