Abstract
Waveguide module assemblies for vehicles, such as radar sensor waveguide feed to waveguide transition assemblies. In some embodiments, an antenna module may comprise an antenna assembly that includes a resonating element and a waveguide component that defines, at least in part, a waveguide configured to guide electromagnetic energy radiating from the resonating element. The resonating element of the antenna assembly may directly feed electromagnetic energy into the waveguide defined by the waveguide component.

A waveguide module, comprising:
- a feed component, the feed component comprising a conductive ground layer, a conductive top layer, and a substrate disposed between the conductive ground layer and the conductive top layer, the conductive top layer comprising:
- a first portion defining a resonating patch coupled to a feed input of the waveguide module by a feed, and
- a second portion conductively isolated from the first portion and coupled to the conductive ground layer by a plurality of conductive vias defined in the substrate;
- and
- a waveguide component, the waveguide component comprising a plurality of posts, the plurality of posts at least in part defining a waveguide, the waveguide component being coupled with the feed component such that the resonating patch directly feeds the waveguide, the waveguide defining a waveguide output of the waveguide module, and wherein the plurality of posts comprises:
- at least a first row of posts defining a first side of the waveguide;
- and
- at least a second row of posts defining a second side of the waveguide opposite the first side of the waveguide.
