摘要： 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.

摘要： In one example, a semiconductor device, includes a substrate having a substrate top side, a substrate bottom side, a substrate dielectric structure, and a substrate conductive structure. The substrate conductive structure includes a transceiver pattern proximate to a substrate top side. An antenna structure includes an antenna dielectric structure coupled to the substrate top side, an antenna conductive structure having an antenna element, and a cavity below the antenna element. The antenna element overlies the transceiver pattern. The cavity includes a cavity ceiling, a cavity base, and a cavity sidewall between the cavity ceiling and the cavity base. Either a bottom surface of the antenna element defines the cavity ceiling and a perimeter portion of the antenna element is fixed to the antenna dielectric structure, or the antenna dielectric structure includes a body portion having a bottom surface that defines the cavity ceiling and the antenna element is vertically spaced apart from the bottom surface of the body portion. An semiconductor component is coupled to a bottom side of the substrate and is coupled to the transceiver pattern. Other examples and related methods are also disclosed herein.

摘要： An efficient, low-profile, lightweight fixed-beam (constant angle of departure) aperture antenna. The aperture antenna includes an array of horn radiators coupled to a waveguide diplexer by means of a stripline distribution network. The stripline distribution network is embedded in a printed wiring board (PWB), which PWB is sandwiched between a radiator plate (incorporating the horn radiators) and a diplexer plate. The aperture antenna may further include a backside ground plane made of metal. The diplexer plate and backside cover plate are configured to form the waveguide diplexer. Each horn radiator has a respective circular opening at one end adjacent to the PWB. The diplexer plate includes an array of circular waveguide backshorts which are congruent and respectively aligned with the circular openings of the horn radiators. The radiator plate further includes a rectangular waveguide backshort which is congruent and aligned with a rectangular port of the diplexer plate.

摘要： A coupling assembly for a first device having a bayonet is provided. The coupling assembly includes a top plate, a bottom plate, and first fasteners securing the top and bottom plates to one another. The top plate having a slot along a connection axis, where the slot receives the bayonet. The bottom plate has a locking arm in axial alignment with the slot and a biasing arm in a region that is radially offset from the locking arm. The region of the bottom plate receives the bayonet, when in a locked position, with the locking arm preventing the bayonet, by interference with locking arm, from rotating about the connection axis back into alignment with the slot and with the biasing arm preventing the bayonet, by interference with biasing arm, from being withdrawn axially along the connection axis.
