A study on antennas for railway millimeter-wave radio communication system

This paper first presents an outline of a new train radio communication system between trains and ground facilities, forming a multimedia railway information and communication system for train operation and passengers, that we have proposed for aiming high-speed and large-capacity communication such as multi-channel quasi-videos. This paper then studies antennas used for mobile radio station and radio base station. Also, this paper describes performance estimation of this proposed antennas, obtained by computer simulation. Results of estimation show that this proposed antenna system has a high degree of feasibility.
