Patent ID: 8536955

Claim:
An integrated microwave waveguide comprising: a waveguide block; a first waveguide section in the waveguide block; a second waveguide section in the waveguide block; a first impedance transition section integrated with the first waveguide section in the waveguide block, wherein the first impedance section comprises a first conduit with a first end and a second end, wherein the first conduit is tapered from the first end to the second end; and a second impedance transition section integrated with the second waveguide section in the waveguide block, wherein the second impedance section comprises a second conduit with a third end and a fourth end, wherein the second conduit is tapered from the third end to the fourth end, and wherein the second end of the first impedance transition section and the fourth end of the second impedance transition section are connected at an antenna stub.
