Abstract
A motor vehicle radar sensor having an antenna arrangement includes a focusing element and at least three first exciter elements which, in conjunction with the focusing element, constitute at least three principal lobes which overlap at most partially and which are switchably or permanently connectable or connected to first transmission and/or reception circuits of the radar sensor, such that at least one further exciter element is present, which is connected directly in parallel with one of the first exciter elements in such a way that these two exciter elements obtain their signals together from the same transmission circuit, and deliver them together to the same reception circuit. An arrangement of this kind makes it possible to produce in the antenna diagram of the radar sensor a shoulder-like protrusion of a principal lobe which advantageously expands the observable angular region, particularly in the close-in range.
