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).
Claims15
A motor-vehicle radar system, comprising:
- at least one housing;
- at least one send/receive element for at least one of sending and receiving an electromagnetic wave;
- at least one first dielectric member arranged in a beam path of the electromagnetic wave;
- and
- at least one arrangement of electrical conductor tracks that are in direct contact with the at least one first dielectric member, wherein:
- an electric power is supplied to the electrical conductor tracks,
- the electrical conductor tracks heat the at least one first dielectric member, and
- the electrical conductor tracks are made of a material having an ohmic resistance that increases substantially with rising material temperature.
