Initial results of multielement antenna performance in 5.85 GHz vehicle-to-vehicle scenarios

Advanced traffic telematics aim to reduce traffic breakdown and enhance driver safety by means of cooperative scheduling between multiple radio frequency access techniques. Those are covering navigation-, cellular- and vehicle-to-vehicle (V2V)- and vehicle-to-infrastructure (V2I)- based services forming true multistandard traffic telematics. V2V and V2I is based on frequency designations in the 5.85 GHz band which is reserved for exclusive road- and drive safety- as well as broadband infotainment applications. This paper introduces a novel and automotive-grade antenna concept that meets the required multistandard approach. It additionally evaluates the potential of multi-antenna V2V- and V2I operations in the 5.85 GHz domain by means of diversity combining or spatial multiplexing to enhance link quality or increase channel capacity.
