Abstract: An antenna for high-frequency based measuring devices for determining a dielectric value of media is based on a high-frequency waveguide. The high-frequency signal is coupled in or out via a coaxial conductor that runs orthogonally through the axis of the high-frequency waveguide for this purpose. The conductor termination for the coaxial conductor extends extensively beyond the high-frequency waveguide in such a way that the coaxial conductor forms a defined capacitance in this region. In this way, the coaxial conductor is optimally matched to the high-frequency waveguide without having to integrate additional electrical components for this purpose.

Abstract: The present disclosure relates to a high-frequency plug connection for high-frequency-based field devices, consisting of plugs and corresponding sockets. The high-frequency plug connection is characterized in that the at least one plug is resiliently enclosed by an enclosure such that this/these plug(s) is/are moveable radially with respect to its/their plugging axis. This has the advantage of reducing the risk of jamming against the enclosure when the plugs are inserted in the corresponding sockets, during fastening of the circuit board substrate on which the sockets are arranged. A modular design of the high-frequency-based field device, and the manufacturability thereof, are simplified as a result.

Abstract: An antenna assembly for emitting microwaves comprises a dielectric hollow conductor element and a support element, wherein the hollow conductor element has an electrically conductive surface along a circumferential lateral face, the hollow conductor element has an electrically non-conductive emission face, and the hollow conductor element has a coupler receptacle. The support element contains a material having a modulus of elasticity of no less than 50 GPa. The support element surrounds the hollow conductor element at least along the lateral face. The hollow conductor element is fixed in the support element. The support element has an emission opening, and the emission face aligns with the emission opening. The hollow conductor element has a permittivity of no less than 8 at 2 GHz, the hollow conductor element containing a ceramic material, in particular aluminium oxide, zirconium oxide or titanium oxide.
