Reliable communications between railway vehicles in a train involves using two antenna pairs of different polarization at both ends of each railway vehicle connected by waveguides

摘要

The reliable communications method involves using two antenna pairs (11-18) of different polarization at both ends of a railway vehicle (1-3) that are directed towards the corresponding antennas of the adjacent railway vehicles and that are connected to the antennas on the same sides at the other end of the same vehicle via waveguides (20,21).
