Abstract
A radar sensor for motor vehicles. The radar sensor includes an antenna arrangement having multiple antenna elements linearly arranged at uniform distances along a connecting line, the distance between each two adjacent antenna elements being equal to half of the mean wavelength λ of the emitted radar signal, and the arrangement including at least one triple of adjacent antenna elements, in which the two antenna elements located on the outside in the triple, on the one hand, and the interposed antenna element, on the other hand, originate in opposite directions from the connecting line. The antenna arrangement includes at least one pair of antenna elements which originate in opposite directions from the connecting line and whose distance from one another is an integer multiple of the wavelength λ, so that one of these antenna elements has a negative amplitude taper in relation to the antenna elements of the triple.
