Abstract

The device (15.1) has a set of antenna element rows (15a, 15b) arranged in a plane in a vertical or a horizontal direction, where the rows have antenna elements (24), patch elements and phase centers (23a, 23b) and pushed opposite to each other in the direction. A cylindrical lens (25) is arranged such that antenna radiations (26a, 26b) starting from the rows are focused at different vertical or horizontal angles. The rows exhibit directional characteristics and phase differences deviating from each other in the vertical or horizontal direction. An independent claim is also included for a device comprising a controller connected with a radar sensor device.

Description

technical field [0001] The invention relates to an antenna arrangement for a radar sensor device, which has a plurality of antenna element rows arranged parallel to one another in the vertical or horizontal direction in a plane, the antenna element rows each having at least two antenna elements, In particular, the patch elements and associated phase centers are arranged at a distance from the beam-forming cylindrical lenses. Furthermore, the invention relates to a radar sensor device and a device, in particular a driver assistance system of a motor vehicle. Background technique [0002] In motor vehicles, radar sensors are increasingly being used to detect the traffic environment within the scope of driver assistance systems, e.g. for radar-supported distance regulation ( A adaptive C ruin C ontrol-Systeme / ACC: Adaptive Cruise Control). Such a motor vehicle speed control system is disclosed, for example, in "Adaptive Fahrgeschwindigkeitsregelung ACC" by Robert Bosch GmbH...
