Effect of car antenna position on radio propagation characteristics at intersection for 760MHz inter-vehicle communications
In the development of the inter-vehicle communication systems for the prevention of car crashes, it is important to know characteristics of radio wave propagation at blind intersections. In the analysis of radio propagation characteristics, a λ/2 dipole antenna is assumed to be the wave source in many cases. However, it is necessary to analyze radio propagation characteristics considering the car body. The reason why is that the directivity of car antenna is changed due to the effect of car body. Additionally, the directivity of car antenna is also changed by the effect of antenna position on car body. In this paper, the effect of car antenna position on radio propagation characteristics at a blind intersection is investigated. Here, the hybrid method using both the FDTD and ray-tracing methods is used for the electromagnetic analysis.
