1. A radar system, the radar system comprising:
a radar circuit configured to generate and process radar signals, the radar circuit comprising a ground plane connector for an electrical connection with an antenna ground plane;
a radar antenna assembly including at least one antenna element configured to transmit radar signals into a traffic space and to receive radar signals reflected by objects present in the traffic space; and
a component of a vehicle,
the ground plane connector electrically connected to the component of the vehicle, wherein:
the component of the vehicle includes a front surface, a rear surface that opposes the front surface, and includes at least one duct that extends between the front surface and the rear surface,
the radar circuit is arranged at the rear surface of the component, and
the at least one antenna element of the radar antenna assembly is arranged at the front surface of the component and connected to the radar circuit via a waveguide member guided through the at least one duct.
