[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] The base station system in a vehicle-ground wireless communication system of the present invention, such as figure 2 As shown, it includes a base station, a power splitter 2, a ground-facing rear antenna 4, a ground forward antenna 41, and a slit waveguide antenna 5. The power splitter 2 is connected to the base station, the ground-facing rear antenna 4, and the ground forward antenna 41 through a feeder. The slotted waveguide antenna 5 is connected to communicate through two different types of communication methods: a ground antenna and a slotted waveguide antenna. The ground-facing rear antenna 4 and the ground-forward antenna 41 forward and backward are relative terms. The real front and rear correspond to the direction of the train. Setting two antennas in opposite directions can extend the transmission distance, reduce the number of base stations, an...
