Abstract:
A signal line to waveguide transformer optimized for operation at an operating frequency comprising:a substrate having first and second major surfaces and first, second, third, and fourth minor surfaces, said second major surface having a conductive material thereon electrically connected to reference potential, said third and fourth minor surfaces defining an electrical short on said second major surface,a length of conductive trace for carrying an electrical signal disposed on said first major surface of said substrate,a waveguide integrally formed from at least a portion of said first major surface of said substrate, said waveguide electrically coupled to said conductive trace and defining a direction of signal propagation disposed on said first major surface of said substrate from said conductive trace toward said waveguide, andat least one transmission line disposed on said first major surface of said substrate, electrically connected to said conductive trace, oriented perpendicularly relative to the direction of signal propagation.
