Abstract

A motor-vehicle radar system provided with at least one housing includes at least one send/receive element for sending and/or receiving electromagnetic waves, at least one first dielectric member in the beam path of the electromagnetic waves, and at least one arrangement of electrical conductor tracks which are in direct contact with the first dielectric member. It is possible to supply an electric power to the electrical conductor tracks, the electrical conductor tracks preferably being used to heat the first dielectric member, and the electrical conductor tracks being made of a material having a pronounced, positive temperature coefficient (PTC characteristic).
