Abstract: A shielding element at least partially shields electromagnetic energy radiating from an electronic component. The shielding element includes an inner wall adapted to face the electronic component when assembled. The inner wall includes a material configured to at least partially reflect the electromagnetic energy radiating from the electronic component. The inner wall includes a structure adapted to interfere with at least one of the radiated or reflected electromagnetic energy.

Abstract: This document describes techniques, apparatuses, and systems utilizing a high-isolation transition design for differential signal ports. A differential input transition structure includes a first layer and a second layer made of a conductive metal and a substrate positioned between the first and second layers. The second layer includes a first section that electrically connects to a single-ended signal contact point and to a first contact point of a differential signal port. The first section includes a first stub based on an input impedance of the single-ended signal contact point and a second stub based on a differential input impedance associated with the differential signal port. The second layer includes a second section that electrically connects to a second contact point of the differential signal port and to the first layer through a via housed in a pad. The second section includes a third stub associated with the differential input impedance.

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: 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.

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.
