Abstract: Reliable electrical contact is made with electronic components and effective electrical isolation is produced between the top and bottom of the electronic components. An electronic component is arranged inside a window in a first layer on a substrate. Next, a second layer is put on such that contact areas on the component and contact points on the first layer are freely accessible. Electrical contacts and electrical connecting lines are produced by electrodeposition. The second layer is used to produce bridges over an interval range between the electronic component and the first layer. The bridges have connecting lines formed on them. The second layer can be removed again. Radio-frequency modules can be produces in compact fashion and can be combined with audio-frequency components.

Abstract: A radar system for measuring the angular position of a remote object has an antenna which is provided with at least two receiving antennae, a transmitter connected to the antenna for transmitting a transmitted signal, a first receiver connected to the first reception antenna for receiving the transmitted signal reflected by the remote object in the form of a first received signal, and a second receiver connected to the second reception antenna for receiving the transmitted signal reflected by the remote object in the form of a second received signal. The first receiver is provided with a first element for determining the first phase of the first received signal and the second receiver is provided with a second element for determining the second phase of the second received signal.

Abstract: A filter module suitable for the filtering of electromagnetic waves includes a dielectric cylindrical resonator and one or more lines that supply or draw off electromagnetic waves to or from the dielectric resonator. The lines terminate in a contacting structure. The resonator has a variable separation from the lines, whereby the separations may be conceived in both the negative as well as alternatively in the positive longitudinal direction (z-axis) of the resonator. The transmitted signal power may be significantly increased in an advantageous manner relative to conventional coupling structures by means of the above. The above is particularly suitable for application in oscillator circuits with operating frequencies above 18 GHz, such as typically find increasing application in environment systems of a motor vehicle such as Lane Departure Warning (LDW), Blind Spot Detection (BSD) or Rear View Detection.
