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: An illustrative example embodiment of an antenna device includes a substrate, a plurality of antenna elements supported on the substrate, an integrated circuit supported on one side of the substrate, and a metallic waveguide antenna situated against the substrate. The metallic waveguide antenna includes a heat dissipation portion in a thermally conductive relationship with the integrated circuit. The heat dissipation portion is configured to reduce a temperature of the integrated circuit.

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: A ball-grid-array printed-circuit-board assembly includes a die, a plurality of solder-balls, a substrate, a top-metal layer, and a bottom-metal layer. The die includes a signal-out-pad and a plurality of ground-pads arranged about the signal-out-pad. The top-metal layer, a plurality of vias in the substrate, and the bottom-metal layer cooperate to form a substrate-integrated-waveguide. The top-metal layer is configured to define a U-shaped-slot between a signal-portion of the top-metal layer aligned with the signal-out-pad and the substrate-integrated-waveguide, and a ground-portion of the top-metal layer aligned with the plurality of ground-pads. The U-shaped-slot is characterized by a slot-length that is selected based on the frequency of a signal, and a slot-width that is selected based on the via-height such that the signal generates an electric field directed across the U-shaped-slot whereby the signal is propagated from the signal-portion of the top-metal layer into the substrate-integrated-waveguide.
