Abstract
Antenna assemblies for vehicles, such as RADAR sensor antenna assemblies, and related waveguide assemblies. In some embodiments, the assembly may comprise a waveguide groove having a waveguide ridge positioned therein. The waveguide groove may extend along an axis with the waveguide ridge intermittently extending on opposite sides of the axis in a periodic or at least quasiperiodic manner along at least a portion of the waveguide ridge. An antenna structure, such as a plurality of slots, may be operably coupled with the waveguide ridge and may be positioned and configured to deliver electromagnetic radiation from the waveguide groove therethrough.
