Abstract: Provided is a radar system, comprising: an antenna printed circuit board (1) comprising at least one transmit antenna and at least one receive antenna; a radar control module (3); an adhesive layer (2) provided between the antenna printed circuit board (1) and the radar control module (3); and vertical feed lines (4, 5, 55) respectively connecting the at least one transmit antenna and the radar control module (3) and respectively connecting the at least one receive antenna and the radar control module (3); whereby the adhesive layer (2) comprises at least one cut-out region (8, 60) being structured by having a non-straight side boundary to direct an electromagnetic wave emanating from a first vertical feed line (4) away from arriving at one or more of the vertical feed lines (4, 5, 55).

Abstract: Provided is a radar sensor comprising at least one antenna 1 having a FOV 2, at least one RF absorber 9, and a radome 3 covering the at least one antenna 1 and the at least one RF absorber 9, wherein the at least one RF absorber 9 is provided with a top surface 10 comprising at least one scattering structure configured to redirect radar waves out of the FOV 2 and to increase radar wave scattering interactions with the radome 3 and the at least one RF absorber 9. As a result, energy of scattered waves and of backwards radiation is reduced. Further, the amount of RF absorber material is reduced and the RCS of the radar sensor is reduced.

Abstract: The present invention relates to a method (1o) for determining an elevation angle of an electromagnetic sensor mounted in a vehicle, wherein the method comprises the steps of exciting (11) a transmitter of the sensor with a plurality of different frequencies such that the transmitter radiates a plurality of first electromagnetic signals corresponding to the plurality of frequencies onto a target arranged in the field of view of the sensor, wherein each of the plurality of first electromagnetic signals is radiated at a different angle relative to the transmitter; receiving (12), by the sensor, a plurality of second electromagnetic signals being reflections of the first electromagnetic signals at the target; determining (13-17) the elevation angle of the sensor based on the second electromagnetic signals. The invention also relates to a corresponding sensor and a computer program for performing the method.
