The data capacity of Euro-balise is 1023 bit, which could not fully satisfy the demanding in field as the existing railway in China is more complicated than that in Europe. This paper proposes a dual-channel balise. Compared with Euro-balise which has one uplink antenna, the new balise adopts two independent uplink antennas with two uplink channels and the data capacity is 2046 bit. Based on electromagnetic field theory, multiple antennas are equivalent to a multi-port network. The S-parameters are simulated and the isolation or mutual coupling among three antennas is analyzed. The distance between two antennas and operation frequency difference are the main influencing factors of mutual coupling. The experiment is implemented on the test platform, the results indicate that the interaction of multi-antenna do not influence the normal work of dual-channel balise.
