    • 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.
    • 具有天线装置的机动车辆雷达传感器包括聚焦元件和至少三个第一激励器元件,其与聚焦元件一起构成至少三个主瓣,其最多部分重叠,并且可切换地或永久地连接或连接到 雷达传感器的第一传输和/或接收电路,使得存在至少一个另外的激励器元件,其直接与第一激励器元件中的一个并联连接,使得这两个激励器元件从 相同的发送电路,并将它们一起发送到相同的接收电路。 这种布置使得可以在雷达传感器的天线图中产生主瓣的肩状突起,其有利地扩展了可观察的角区域,特别是在接近的范围内。
