Claim 0:
1. An apparatus comprising:
a waveguide that includes a printed circuit board (PCB) having a first substrate layer, a second conductive layer, and a third layer, the waveguide including:
a hollow channel for a dielectric that includes a first opening in a longitudinal direction through the hollow channel at one end of the waveguide and a closed wall at an opposite end of the waveguide, the third conductive layer forming a surface of the hollow channel that defines the hollow channel, the hollow channel forming a zigzag shape along the longitudinal direction, the zigzag shape comprising multiple turns along the longitudinal direction, each of the multiple turns having a turning angle greater than 15 degrees and less than 75 degrees; and
a plurality of radiation slots, each of the plurality of radiation slots comprising a second opening formed in the second conductive layer, each of the plurality of radiation slots being operably connected with the dielectric through the hollow channel and positioned along a centerline of the hollow channel that is parallel with the longitudinal direction, each of the plurality of radiation slots being a longitudinal slot parallel to the longitudinal direction and having a rectangular shape, wherein the plurality of radiation slots form a single straight line.
