Abstract

Waveguide and/or antenna structures for use in RADAR sensor assemblies and the like. In some embodiments, the assembly may comprise a waveguide block comprising a first surface on a first side of the waveguide block and a second surface on a second side of the waveguide block opposite the first side. One or more waveguides may be formed in the waveguide block. One or more antenna slots may be operably coupled with one or more of the waveguides. One or more auxiliary grooves may be positioned adjacent to at least one of the antenna slots and may mimic, or at least substantially mimic, at least one of the one or more antenna slots, such as in length and/or width.
