Abstract
Waveguide and/or antenna structures for use in RADAR sensor assemblies and the like comprising unique antenna slot transitional features. In some embodiments, an antenna module for a vehicle sensor may comprise a waveguide having a waveguide ridge extending therein. The waveguide ridge may comprise an elongated axis along which the waveguide ridge extends. An antenna slot may be operably coupled with the waveguide and may comprise an elongated axis along which the antenna slot extends. The elongated axis of the antenna slot may be at least substantially aligned with or at least substantially parallel to the elongated axis of the waveguide ridge.
Claims20
An antenna module for a vehicle sensor, comprising:
- a waveguide;
- a waveguide ridge extending within the waveguide, wherein the waveguide ridge comprises an elongated axis along which the waveguide ridge extends;
- and
- an antenna slot operably coupled with the waveguide, the antenna slot comprising an elongated axis along which the antenna slot extends, wherein the elongated axis of the antenna slot is at least substantially aligned with or at least substantially parallel to the elongated axis of the waveguide ridge.
An antenna module, comprising:
- a plurality of waveguides;
- a plurality of waveguide ridges, each waveguide ridge of the plurality of waveguide ridges being positioned and extending within a corresponding waveguide of the plurality of waveguides;
- and
- a plurality of antenna slots, each antenna slot of the plurality of antenna slots being positioned within a terminal end of a corresponding waveguide of the plurality of waveguides,
- wherein each antenna slot of at least a subset of the plurality of antenna slots is positioned in a non-centered configuration within the terminal end of its corresponding waveguide.
An antenna module, comprising:
- a plurality of waveguides;
- and
- a plurality of antenna slots, each waveguide ridge extending towards and terminating adjacent to a corresponding antenna slot, wherein each antenna slot of the plurality of antenna slots defines an elongated axis that is non-perpendicular to the waveguide ridge axis of its corresponding waveguide ridge.
