  Abstract

This paper proposed implement and validate Vehicle Inner directional antenna that can be applied to C-ITS (Cooperative Intelligence Transport Systems) that will lead to innovative changes in traffic safety. In order to activate C-ITS, convenience and ease of installing antenna considering V2X communication area and user side should be secured. Car antennas can generally consider external antennas of the Shark antenna type installed in the vehicle top loop. In the case of an antenna for external use of a vehicle, it is an optimal position to secure antenna characteristics, but if there is an antenna for other purposes of the vehicle, additional installation and vehicle modification are necessary and cable wiring is difficult. This paper proposed in order to activate C-ITS, Vehicle Inner directional antenna that can achieve the same level of performance as an external antenna for a vehicle. In order to secure the poor environmental characteristics, fading, and installation convenience in the interior of the vehicle, a circularly polarized microstrip patch array antenna, which is a typical high gain flat antenna, was selected and secured through antenna fabrication and tuning. The proposed antenna has a central frequency of 5890㎒ and an impedance bandwidth of 110㎒(VSWR<1.5). In the WAVE communication band(5.855 ~ 5.925㎓), The half power beam width(HPBW) satisfies 20°(yz-plane) and 73°(zxplane) at center frequency. In order to verify the performance of the proposed antenna, the performance of the interior antenna was verified by measuring the Vehicle-to-Vehicle(V2V) communication area and measuring the Vehicle-to-Infrastructure(V2I) demonstration service. Performance verification confirmed satisfaction with C-ITS application.
