Abstract:
A multi-beam radar sensor having at least two transmitter/receiver elements (6) on a substrate (7), having a focusing body (1), which is assigned to each transmitter/receiver element (6) for prefocusing the beam path, having a mount (4) for the focusing body (1), and having a dielectric lens (8) which is disposed in the beam path of the transmitter/receiver element (6) and of the focusing body (1), characterized in that the mount (4) is embodied with regard to its material, its geometric dimensions and its contact points with the focusing bodies (1) in such a way that the coupling of energy to the adjacent focusing body (1) is minimized, and wherein the mount (4) is embodied with a recess (5) between the focusing bodies (1).
