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).

Automotive radar system

Lens arrangement suited for focusing radar waves

A motor vehicle radar sensor having an antenna arrangement includes a focusing element and at least three first exciter elements which, in conjunction with the focusing element, constitute at least three principal lobes which overlap at most partially and which are switchably or permanently connectable or connected to first transmission and/or reception circuits of the radar sensor, such that at least one further exciter element is present, which is connected directly in parallel with one of the first exciter elements in such a way that these two exciter elements obtain their signals together from the same transmission circuit, and deliver them together to the same reception circuit. An arrangement of this kind makes it possible to produce in the antenna diagram of the radar sensor a shoulder-like protrusion of a principal lobe which advantageously expands the observable angular region, particularly in the close-in range.

Motor vehicle radar sensor

Microwave antenna array for a motor vehicle radar system

In a device for directional transmission and/or receiving of electromagnetic waves, including at least one antenna element and a dielectric lens, there is arranged between them a prefocusing dielectric body for avoiding overradiation of the lens. In order to simplify adjustment, the lens has an extended surface, is preferably pot-shaped, and forms, in conjunction with a baseplate, a hermetically sealed housing for unencapsulated ICs.
