Abstract
Waveguide and/or antenna structures for use in RADAR sensor assemblies and the like. In some embodiments, the assembly may comprise a structure defining a waveguide groove on a first side of the structure and an antenna slot formed on a second side of the structure opposite from the first side. A thru-hole may extend through the structure between the antenna slot and the waveguide groove. The thru-hole may comprise an axis and a width measured between opposing sidewalls extending at least substantially perpendicular to the axis. The width may be less than a corresponding width of the waveguide groove.
Claims17
A combined waveguide and antenna structure, comprising:
- a waveguide groove extending along an elongated axis on a first side of a unitary structure, wherein the waveguide groove comprises a width defined between opposite sidewalls defining the waveguide groove;
- and
- an antenna structure operably coupled with the waveguide groove, wherein the antenna structure comprises:
- an antenna slot extending along an elongated axis coextensive with the elongated axis of the waveguide groove on a second side of the unitary structure opposite from the first side, wherein the antenna slot is positioned and configured to deliver electromagnetic radiation from the waveguide groove therethrough, wherein the antenna slot is coupled with the waveguide groove via a thru-hole, wherein the antenna slot comprises a width extending between opposite sidewalls defining the antenna slot, and wherein the width of the waveguide groove is greater than the width of the antenna slot.
A vehicle sensor assembly, comprising:
- a waveguide groove;
- an antenna slot operably coupled with the waveguide groove and configured to deliver electromagnetic radiation from the waveguide groove therethrough;
- a first elongated groove extending adjacent to and at least substantially parallel to the antenna slot, wherein the first elongated groove is spaced apart from a first side of the antenna slot, and wherein the first elongated groove is a non-radiating structure;
- and
- a second elongated groove separate from the first elongated groove and extending adjacent to and at least substantially parallel to a second side of the antenna slot opposite from the first side, wherein the second elongated groove is spaced apart from the second side of the antenna slot, and wherein the second elongated groove is a non-radiating structure, wherein the waveguide groove is operably coupled to the antenna slot via an elongated thru-hole, wherein the waveguide groove comprises a width extending between opposing walls defining the waveguide groove, and wherein the width of the waveguide groove is greater than a corresponding width of the elongated thru-hole, and wherein the antenna slot comprises a width extending between opposing walls defining the antenna slot, and wherein the width of the antenna slot is greater than the width of the elongated thru-hole.
A vehicle sensor assembly, comprising:
- a structure defining a waveguide groove on a first side of the structure;
- an antenna slot formed on a second side of the structure opposite from the first side;
- and
- a thru-hole extending through the structure between the antenna slot and a base of the waveguide groove, wherein the thru-hole comprises an axis and a width measured between opposing sidewalls extending at least substantially perpendicular to the axis, wherein the width is less than a corresponding width of the waveguide groove, and wherein the width is less than a corresponding width of the antenna slot.
