Abstract
Waveguide and/or antenna structures for use in RADAR sensor assemblies for vehicles and the like. In some embodiments, the assembly may comprise an antenna slot array comprising a plurality of antenna slots extending between opposing surfaces of a unitary structure of the antenna assembly, such as a waveguide and/or antenna block. A plurality of elongated grooves may be positioned adjacent to at least one of the antenna slots of the antenna slot array. Each of at least a subset of the plurality of elongated grooves may be defined, at least in part, by a ridge formed along an antenna side of the unitary structure.
