Examples disclosed herein relate to an autonomous driving system in an ego vehicle. The autonomous driving system includes an antenna system having an antenna controller configured to provide a radar transmission signal for transmission to a target. The antenna system also includes a beacon circuit coupled to the antenna controller and configured to generate a superimposed signal comprising the radar transmission signal and a beacon signal having information that identifies the ego vehicle to other vehicles that are in a range distance of the ego vehicle. The antenna system also includes a metamaterial antenna structure coupled to the beacon circuit and configured to transmit the superimposed signal to the other vehicles. Other examples disclosed herein include a radar system having a beacon system and a method of operating the antenna system in the autonomous driving system of the ego vehicle, for vehicle identification.
