    摘要: An antenna system for radar sensors, for example in vehicles (automatic adaptive cruise control system (ACC)), having at least one planar group antenna (10) which comprises a feed line (14) and a plurality of antenna elements (16, 18) which are integrated into the feed line. The group antenna (10) has at least two antenna gaps (20, 22) which run parallel to one another and which are connected to one another at one end via a bypass line (24). The length of said bypass line (24) is dimensioned such that the antenna gaps are overall in phase with one another. The power which still remains at the end of the first antenna gap does not need to be reflected but instead is irradiated via the antenna elements of the second antenna gap. The phase and amplitude assignments are selected such that the directional characteristic is improved.
