Abstract

A sensor device for a motor vehicle, including a first transmitting antenna, which is situated on a surface of a substrate, has a narrow lobe-type directional characteristic and includes a defined number of planar antenna elements; a second transmitting antenna situated on the surface of the substrate has a wide lobe-type directional characteristic, including a defined number of planar antenna elements, the directional characteristics of the two transmitting antennas being oriented opposite one another by a defined angle, with respect to a boresight; and at least one receiving antenna situated on the surface of the substrate including a defined number of planar antenna elements.
