Abstract: A radome for a radar sensor in a motor vehicle. The radome includes a first region, which is permeable to at least one specific type of electromagnetic waves, in particular radar waves, and a second region, which includes a shield, so that the second region is impermeable to the specific type of electromagnetic waves. Also, a radar sensor is described.

Abstract: The invention relates to a radar sensor including a radar antenna, a radar lens and a funnel element between the radar antenna and the radar lens. The funnel element includes a material which absorbs the radar radiation emitted by the radar antenna.

Abstract: An angle-resolving radar sensor for motor vehicles having multiple antenna elements and multiple receive channels, at least two antenna elements connected to the same receive channel together having a directional characteristic having at least two main lobes having different primary sensitivity directions.

Abstract: A radar system for motor vehicles has at least two radar sensors for emitting and receiving radar radiation for monitoring the surroundings of the motor vehicle, the at least two radar sensors being each positioned at an angle between 40 degrees and 50 degrees to an axis, and the at least two radar sensors being configured in such a way that the respective antenna has a pivotable visual range of an angle between at least ?60 degrees and +60 degrees, in particular between ?45 degrees and +45 degrees, relative to the main emission direction of the respective radar sensor.

Abstract: A radar sensor for motor vehicles, having an antenna system that can be controlled by a control device so that it has a temporally varying directional characteristic, and having an evaluation device for evaluating the radar echoes received by the antenna system and for the location of objects using angular resolution, wherein the antenna system has at least two groups of antenna elements that differ in elevation in their effective direction, and the control device is fashioned to activate and deactivate the two groups in periodically alternating fashion, and the evaluation device is configured to estimate the elevation angle of the objects on the basis of a contrast between the radar echoes received by the various groups.

Abstract: A radar sensor for motor vehicles, having a transmitting antenna in the form of a planar group antenna having multiple antenna elements situated side by side on a shared planar substrate, and having a feed network and a switching device for supplying microwave power to the antenna elements. The antenna elements are situated at equal distances in at least one row; the feed network is designed for supplying the antenna elements with the microwave power having a phase shift which increases at constant increments from one end of the row to the other; and the switching device is designed for controlling the supply of the microwave power to the antenna elements in such a way that, depending on the operating mode, the supply is implemented in a mirror-inverted fashion from opposite ends of the at least one row.

Abstract: A planar array antenna for radar sensors includes: a plurality of base antenna elements situated in a common plane on a printed circuit board; and additional antenna elements, which are situated in an offset plane, in each case over one of the base antenna elements. Each additional antenna element is situated individually on an associated carrier, and the printed circuit board is equipped with the individual carriers.

Abstract: An array antenna for radar sensors has a supply line, a plurality of antenna elements each connected to the supply line via a feed line, and circuit elements for distributing power to the antenna elements, in which the supply line is made reflective at one end and the circuit elements for power distribution are situated exclusively in the feed lines.
