    Abstract: This document describes techniques, apparatuses, and systems for a multi-layer air waveguide with layer-to-layer connections. Each pre-formed layer of the air waveguide is attached to at least one other pre-formed layer by a mechanical interface. The mechanical interface may be a stud-based interface, a snap fastener-based interface, a ball-and-socket based interface, or a pressure contact interface utilizing irregular roughed surfaces of each pre-formed layer. The mechanical interfaces of the pre-formed layers structurally hold the air waveguide together and electrically couple all of the pre-formed layers. In this manner, the cost of manufacturing the air waveguide antennas may be less expensive than previous manufacturing processes.

    Abstract: This document describes a single-layer air waveguide antenna integrated on a circuit board. The waveguide guides electromagnetic energy through channels filled with air. It is formed from a single layer of material, such as a sheet of metal, metal-coated plastic, or other material with conductive surfaces that is attached to a circuit board. A portion of a surface of the circuit board is configured as a floor of the channels filled with air. This floor is an electrical interface between the circuit board and the channels filled with air. The single layer of material is positioned atop this electrical interface to define walls and a ceiling of the channels filled with air. The single layer of material can be secured to the circuit board in various ways. The cost of integrating an air waveguide antenna on to a circuit board this way may be less expensive than other waveguide-manufacturing techniques.

    Abstract: This document describes facia, including parts of vehicles, for supporting an ultra-wide radar field-of-view, for example, in automotive contexts. The facia is configured as a radome for supporting an ultra-wide field-of-view with an antenna despite the facia obstructing a field of view. The facia has one exterior surface or interior surface this is a mostly smooth or has a pattern of hemispherical indentations or domes that are configured to reduce reflections off that surface and increase light transmission through the facia. The other of the exterior or interior surface, has a pattern of hemispherical indentations or domes that are configured to reduce reflections off that surface and further increase light transmission through the facia.
