Abstract

RADAR sensor assemblies/modules, particularly those for vehicles. In some embodiments, the assembly may comprise a plurality of waveguides, each waveguide of the plurality of waveguides being defined by a waveguide groove. A slot may be positioned to extend along an axis of each of the plurality of waveguide grooves. Each of the waveguides may be further defined, at least in part, by a periodic feature that extends back and forth in a periodic manner along at least a portion of its respective waveguide and a plurality of periodic signal confinement structures, a first periodic signal confinement structure of which may extend adjacent to a first side of each of the plurality of waveguides, and a second periodic signal confinement structure which may extend along a second side of each of the plurality of waveguides opposite the first side.

Dependent claims

A vehicle sensor assembly, comprising:

a waveguide block defining a plurality of waveguides, each waveguide defined by a waveguide groove, wherein at least one of the plurality of waveguide grooves oscillates back and forth between opposing sides of a structure defining the respective waveguide groove in a periodic manner along an elongated axis of its respective waveguide;
an antenna structure operably coupled with plurality of waveguides, wherein the antenna structure comprises an array of one or more slots extending along an elongated axis of each waveguide groove of the plurality of waveguides, wherein each of the one or more slots is configured to deliver electromagnetic radiation from at least one of the plurality of waveguides therethrough, and wherein at least one of:
(1) the plurality of waveguide grooves;
and (2) the one or more slots extends along the elongated axis of its respective waveguide;
and
a substrate comprising a plurality of electromagnetic feed structures, wherein each of the plurality of electromagnetic feed structures is operably coupled to a corresponding waveguide of the plurality of waveguides to deliver electromagnetic waves through the plurality of waveguides.
