Title: ANTENNA DEVICE FOR A RADAR SENSOR
Abstract:
Antenna device (100) for a radar sensor (200) having: – at least one first antenna group (20) arranged on a surface of a substrate (1) and having a defined number of serially connected planar antenna elements (10); – at least one second antenna group (30) arranged on the surface of the substrate (1) and having a defined number of serially connected planar antenna elements (10); a feed line (12) which is connected to the centre of each of the the two antenna groups (20, 30); – wherein a feed signal can be fed into the antenna group (20, 30) by means of the feed line (12) in such way that a feed signal which is phase-shifted by 180 degrees with respect to the second antenna group (30) can be fed to the first antenna group (20).
