Abstract
Mobile communication for vehicles is a promising technology to increase road safety and traffic efficiency. Advanced driver assistance systems (ADAS) basing on mobile communication have to be validated properly before being deployed in commercial vehicles. Basing on an existing test facility, we have set up an urban intersection aiming to reproduce real world propagation effects. In recent studies, requirements for the building properties were derived in simulations assuming an omnidirectional radiator on the vehicle rooftop for a vehicle-to-vehicle (V2V) blind corner communication. In this paper, a measured radiation pattern of an antenna mounted on a vehicle's rooftop is used for the investigation of wave propagation and compared to the omnidirectional radiator. The measured vehicular antenna is mainly radiating in the upper hemisphere. The horizontal cut shows some distinct nulls and especially in the front half of the car two symmetric lobes. In spite of the large differences in the radiation patterns, the simulations results of wave propagation for the measured antenna pattern are similar to the omnidirectional antenna due to multiple reflections from the surrounding building walls and the roadway.
