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.
