Novel fabrication methods for slotted waveguide antennas

Leaky-wave slot waveguide antennas have a low profile with high gain and power handling capabilities but are typically expensive to fabricate. High fabrication expenses often result in the elimination of this design method from consideration in cost sensitive applications. This paper discusses a novel method of fabrication that reduces the medium to high volume production costs of slotted waveguide antennas to the point that more extensive applications in the civilian sector can be considered.
