Abstract
Antenna and/or waveguide assemblies for vehicles, such as RADAR sensor antenna assemblies, along with associated signal confinement structures. In some embodiments, the assembly may comprise an antenna block defining one or more waveguides. A conductive layer may be coupled to the antenna block to form, at least in part, a wall of the waveguide. The assembly may comprise one or more periodic structures that may be operably coupled to the waveguide, each of which may comprise a first elongated opening and a first series of repeated slots extending at least substantially transverse to the first elongated opening, wherein each of the first series of repeated slots is spaced apart from an adjacent slot in the first series of repeated slots along the first elongated opening.
