Abstract: 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.

Abstract: This document describes a folded waveguide for antenna. The folded waveguide may be an air waveguide and includes a hollow core that forms a rectangular opening in a longitudinal direction at one end, a closed wall at an opposite end, and a sinusoidal shape that folds back and forth about a longitudinal axis that runs in the longitudinal direction through the hollow core. The hollow core forms a plurality of radiation slots, each including a hole through one of multiple surfaces that defines the hollow core. The radiation slots are arranged on the one surface to produce a particular antenna pattern. The radiation slots and sinusoidal shape enable the folded waveguide to prevent grating lobes from appearing in the particular antenna pattern on either side of a horizontal-polarity, main beam, or to prevent X-band lobes from appearing in the particular antenna pattern on either side of a vertical-polarity, main beam.

Abstract: This document describes a waveguide with slot-fed dipole elements. An apparatus may include a waveguide for providing narrow coverage in an azimuth plane. The waveguide includes a hollow channel containing a dielectric and an array of radiation slots through a surface that is operably connected with the dielectric. The waveguide includes an array of dipole elements positioned on or in the surface and offset from each longitudinal side of the array of radiation slots. The radiation slots and the dipole elements configure the described waveguide to focus an antenna radiation pattern that supports a narrow beamwidth.

Abstract: This document describes techniques and systems of an exposed portion of a PCB configured to provide isolation among radar antennas. The described radar system includes an exposed portion of a surface of a printed circuit board (PCB) positioned between a first antenna and a second antenna. The PCB includes a metal plating on the surface of the PCB. A width of the exposed portion can delay a phase of electromagnetic (EM) energy conducted by the metal plating relative to a phase of EM energy that does not traverse the exposed portion. A height of the exposed portion can cause an amount of the EM energy conducted by the metal plating to be approximately equal to an amount of EM energy that traverses the exposed portion. In this way, the described systems and techniques can reduce signal-coupling among radar antennas without additional hardware costs and distance between the antennas.

Abstract: An illustrative example antenna device includes a substrate. A plurality of conductive members in the substrate establish a substrate integrated waveguide. A plurality of first and second slots are on an exterior surface of a first portion of the substrate. Each of the second slots is associated with a respective one of the first slots. The first and second slots are configured to establish a radiation pattern that varies across a beam of radiation emitted by the antenna device. A plurality of parasitic interruptions include slots on the exterior surface of a second portion of the substrate. The parasitic interruptions reduce ripple effects otherwise introduced by adjacent antennas.

Abstract: An illustrative example electronic device includes a substrate integrated wave guide (SIW) comprising a substrate and a plurality of conductive members in the substrate. An antenna member is situated at least partially in the substrate in a vicinity of at least some of the plurality of conductive members. A signal generator has a conductive output electrically coupled with the antenna member. The antenna member radiates a signal into the SIW based on operation of the signal generator.

Abstract: This document describes techniques, apparatuses, and systems for a waveguide with lobe suppression. A waveguide is described that includes a pipe for containing a dielectric, the pipe defining an open end to a longitudinal direction through the pipe. An array of radiating slots is formed through a surface of the pipe and in communication with the dielectric. To suppress grating lobes in an antenna pattern, the waveguide includes at least one parasitic groove that is separate from the pipe and with at least a portion of a length that is parallel to the array of radiating slots. In this way, the waveguide provides an antenna pattern where grating lobes are suppressed or substantially reduced.

Abstract: This document a two-part folded waveguide with horns. For example, a waveguide includes a channel with an opening in a longitudinal direction at one end, and a sinusoidal shape that folds back and forth about a longitudinal axis that runs in the longitudinal direction through the channel. One part of the waveguide defines a surface of the channel featuring a plurality of radiation slots in the shape of a horn, which allows the two parts of the waveguide to be arranged and configured as one component. A first part of the waveguide has slots and an upper half of the walls of the channel and a second part provides a lower half of the walls of the channel and a surface of the channel opposite the slots. Using horns in combination with two parts enables ease of manufacturing a waveguide with an internal channel having a folded or sinusoidal shape.
