To allow for communication even in challenging propagation scenarios (such as busy urban intersection), we investigated a new concept for rooftop mounted beam-steerable vehicular antennas which is a 2-element monopole array (parallel and orthogonal to direction of travel) and a switchless reconfigurable antenna. It shows that the monopole array configurations give the best propagation results in any scenario and time step. However, the beams have to be steered dynamically to ensure the best possible communication.en621conference paper
