Abstract
In described examples, an integrated waveguide transition includes a substrate with a waveguide side and an opposing waveguide termination side. A first layer of metal covers a portion of the waveguide side, a second layer of metal is separated from the first layer of metal by a first layer of dielectric, and a third layer of metal covers a portion of the waveguide termination side and is separated from the second layer of metal by a second layer of dielectric. A substrate waveguide perpendicular to a plane of the substrate extends from the waveguide side to the waveguide termination side; and a length and a width of the substrate waveguide is defined by a fence of ground-stitching vias that short the first layer of metal and the second layer of metal to a plate of the third layer of metal that forms a back short.
