摘要： 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.

摘要： Waveguide and/or antenna structures for use in RADAR sensor assemblies and the like. In some embodiments, the assembly may comprise a waveguide groove extending along an elongated axis on a first side of a block and an antenna structure operably coupled with the waveguide groove. The antenna structure may comprise an antenna slot extending along the elongated axis on a second side of the block opposite from the first side and the antenna slots may be positioned and configured to deliver electromagnetic radiation from the waveguide groove therethrough. Some embodiments may further comprise one or more grooves extending adjacent to the antenna slot, such as opposing grooves extending adjacent to the antenna slot.
