Claim 9:
10. A system comprising:
a waveguide;
a substrate integrated waveguide (SIW) transition coupled to the waveguide, wherein the SIW transition comprises:
a dielectric substrate having a top surface and a bottom surface;
a first metallic layer portion coupled to the top surface of the dielectric substrate, wherein the first metallic layer portion comprises:
a single-ended termination, and
an impedance transformer positioned between the single-ended termination and an open portion in the first metallic layer portion, wherein the impedance transformer tapers from a first end positioned proximate the single-ended termination to a second end positioned proximate the open portion, and wherein the open portion has a rectangular configuration with long sides thereof aligned in parallel to a centerline that extends between the single-ended termination and the impedance transformer;

a second metallic layer portion coupled to the bottom surface of the dielectric substrate; and
a set of metallic via-holes electrically coupling the first metallic layer portion to the second metallic layer portion.
