Title:
RADAR SENSOR HAVING A PLURALITY OF MAIN BEAM DIRECTIONS
Document Type and Number:
WIPO Patent Application WO/2019/081119
Kind Code:
A3
Abstract:
The invention relates to a radar sensor having a plurality of main beam directions (5), said radar sensor comprising a printed circuit board (2), on which one or a plurality of antenna elements (3) are arranged for transmitting and/or receiving radar radiation. Furthermore, the radar sensor has at least one or a plurality of dielectric lenses (6) which are arranged in the beam path (7) of the antenna elements (3), wherein the optical axis (8) of the dielectric lens (6) is tilted in relation to the main beam direction (4) of the at least one or plurality of antenna elements (3) at an angle (12) greater than zero degrees so that at least one main beam direction (5) of the radar sensor is determined with a predetermined angle to the vertical (10) of the printed circuit board surface.
