Abstract
Antenna assemblies for vehicles, such as RADAR sensor antenna assemblies. In some embodiments, the assembly may comprise an antenna block defining an array of waveguide grooves on a first side of the antenna block. A slotted layer comprising a plurality of slots may be coupled with the antenna block with the slots at least partially aligned with the waveguide grooves of the antenna block. An adhesive layer may be positioned in between the antenna block and the slotted layer.
