Abstract: The invention relates to a radar sensor (10) for use with automobiles. Said radar sensor emits pulsed radiation. The radar sensor is characterized in that it comprises an antenna with at least one layer-structured block (34) consisting of metal layers (36, 38, 40, 42) which are arranged according to the Yagi principle and which are respectively separated from each other by a dielectric intermediary layer (46, 48, 50). At least one of the metal layers (36, 38, 40, 42) is excited by a supply system (18) with a radar frequency.

Abstract: The invention presents a radar antennae (10) for motor vehicle applications comprising at least one supply network (18) on a first side (20) of a high-frequency substrate (22), a metallic ground surface (24) on a second side (26) of the high-frequency substrate (22) opposite to the supply network (18), with and at least one radiative surface (28) which is excited by the supply network (18) via an associated aperture (30) in the metallic ground surface (24) and via a dielectric (32) disposed between the ground surface (24) and the radiative surface (28), to radiate electromagnetic waves, and with a housing (12). The radar antennae (10) is characterized in that the radiative surface (28) is firmly connected to the housing (12). The invention also presents a method for producing such radar sensors (10).
