Abstract: A radar arrangement includes a multi-layer printed circuit board, an antenna, an electronic component for generating and converting a high frequency (HF) signal, and a lead structure for guiding the HF signal between the electronic component and the antenna. The circuit board includes a first layer of a carrier material and a second layer of a HF substrate. The electronic component and the antenna are arranged on a component side of the HF substrate. The lead structure is arranged at least in regions on the component side. The component side is cast at least in the region of the electronic component. A metal layer is arranged between the first and second layers. The lead structure is connected to the metal layer in areas via a through-hole such that the through-hole forms a DC short circuit so the lead structure and the metal layer have the same potential during operation.

Abstract: A fill level measuring device having at least one transmitting and receiving unit, a measuring antenna with a first supply element for transmitting and receiving an electromagnetic measurement signal and at least one dielectric body for guiding and/or shaping the waves of the measurement signal, and a communication antenna. The communication antenna has at least one second supply element for wireless transmission and for receiving an electromagnetic communication signal. To provide a fill level measuring device that can be used particularly flexibly, the first supply element and the second supply element are arranged inside the dielectric body so that the dielectric body is able to guide and/or shape the measurement signal and the communication signal.

Abstract: A field device (1) having a switching converter circuit (2) and a measuring circuit (3) for determining at least one measuring variable. The switching converter circuit (2) is supplied with electric power on the input side and the switching converter circuit (2) is connected to the measuring circuit (3) on the output side and the switching converter circuit (2) supplies the measuring circuit (3) with electric power. The problems associated with changing interfering signals due to the switching converter circuit are reduced in that a load circuit (5) is actuated by a load control circuit (6) so that the output-side electric load at the switching converter circuit (2) does not fall below a minimum electric load.
