WAVEGUIDE SENSOR ASSEMBLIES AND RELATED METHODS

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. 本发明提供了用于车辆的天线组件，诸如雷达传感器天线组件。在一些实施方案中，该组件可包括天线块，该天线块限定位于天线块第一侧上的波导槽阵列。包括多个狭槽的开槽层可与天线块联接，其中狭槽至少部分地与天线块的波导槽对准。粘合剂层可以定位在天线块与开槽层之间。
