Abstract: A radar sensor emits microwave radiation and receives partial radiation reflected at objects within the sensor detection range, a plurality of antennas being provided for the transmission and reception in each case, and the transmission power of the outer antennas being lower than the transmission power of the inner antennas. This is accomplished by reducing the transmission power with the aid of couplers, the couplers advantageously being implementable as Wilkinson power splitters.

Abstract: An arrangement for frequency-selective suppression of high frequency signals is described, with a hollow chamber (11) including at least partially electrically conductive walls (6, 7) and having radiator elements (4, 5), embodied by stripline technology, for coupling the high frequency signals into and out of the hollow chamber (11). At least two radiator elements are present, of which at least one is intended for coupling in the high frequency signals and at least one other is intended for outcoupling them. The at least two radiator elements (4, 5) are embodied on separate substrate faces (2, 3). The separate substrate faces (2, 3) are disposed on a common substrate plate (1), and the hollow chamber is formed by a hood (6), which is disposed on or above the substrate plate (1) in such a way that it covers the radiator elements (4, 5). It is especially advantageous if the hood (6) is integrated with the housing wall (10) of a shielding housing.
