摘要: Example embodiments relate to substrate integrated waveguide (SIW) transitions. An example SIW may include a dielectric substrate having a top surface and a bottom surface and a first metallic layer portion coupled to the top surface of the dielectric substrate that includes a single-ended termination, an impedance transformer, and a metallic rectangular patch located within an open portion in the first metallic layer portion such that the open portion forms a non-conductive loop around the metallic rectangular patch. The SIW also includes a second metallic layer portion coupled to the bottom surface of the dielectric substrate and metallic via-holes electrically coupling the first metallic layer to the second metallic layer. The SIW may be implemented in a radar unit to couple antennas to a printed circuit board (PCB). In some examples, the SIW may be implemented with only a non-conductive opening that lacks the metallic rectangular patch.

摘要: A transceiver includes first electrical channels and second electrical channels. The first electrical channels are configured to transfer electromagnetic signals to first air waveguides. Each of the first electrical channels extend from a transmitter along an exterior surface of a chip package that supports the transmitter and terminate at first transitions on the exterior surface. Each of the first plurality of air waveguides are attached to the exterior surface and overlay one of the first transitions. The transceiver also includes second electrical channels configured to transfer second electromagnetic signals from second air waveguides. Each of the second electrical channels extend from a receiver along the exterior surface of the chip package that supports the receiver and terminate at second transitions on the exterior surface. Each of the second air waveguides are attached to the exterior surface and overlay one of the second transitions.

摘要: A printed circuit board is provided, comprising a horizontally extending dielectric substrate and a substrate integrated waveguide (SIW). The SIW comprises two horizontally disposed conductive ground planes spaced by a vertical distance, and two vertically disposed conductive fences spanning therebetween. The fences extend in a first horizontal direction, and are spaced from one another in a second horizontal direction, perpendicular to the first horizontal direction. A space defined between the ground planes and the fences comprises material of the substrate formed with one or more channels being free of material of the substrate and extending in the first horizontal direction. Each of the channels is formed by a plurality of vertical cylindrical cavities, and each cavity horizontally overlaps one or more adjacent cavities.
