Antenna arrangement for a radar sensor

Abstract

The invention relates to an antenna arrangement for a radar sensor, having: an antenna body and a printed circuit board, which form a waveguide antenna. The antenna body has a first surface facing the printed circuit board and a second surface facing away from the printed circuit board. The first surface is formed with a first structure that provides wave interfaces to the printed circuit board and forms a waveguide structure. The antenna body is designed with transmitting and/or receiving structures, and the second surface is formed with a second structure that reduces undesirable surface effects.
