This paper describes the design of RF link between RSE and OBU of ETCS and the analysis of the antenna beam pattern to get a proper communication area in the cross direction and traveling direction of lanes. This stage should be performed prior to determination of system requirements of ITS service based on active DSRC. This study is important and fundamental technical analysis to design and implement base station of ETCS.
