Abstract:
A waveguide device comprising:a first waveguide member aligned along a first axis and configured to carry a first signal having first and second polarities, the first waveguide member having cross-sectional dimensions that decrease along the first axis from a first distal end to a second proximal end thereof; a second waveguide member aligned along the first axis and configured to carry a second signal having at least one polarity, the second waveguide member communicating with the first waveguide member through a first coupling aperture, the second waveguide member having cross-sectional dimensions that decrease along the first axis from a first distal end to a second proximal end thereof, the second proximal end of the second waveguide member being adjacent the second proximal end of the first waveguide member; third and fourth waveguide members in communication with an interior of the first waveguide member, the first signal being separated by the first waveguide member such that the first polarity is carried within the third waveguide member and discharged at a first distal end thereof and the second polarity is carried within the fourth,waveguide member and discharged at a first distal end thereof, the third waveguide member having cross-sectional dimensions that decrease along a second axis from the first distal end to a second proximal end thereof, the fourth waveguide member having cross-sectional dimensions that decrease along a third axis from the first distal end to a second proximal end thereof; and wherein the waveguide device is of an integral cast construction.
