Patent ID: 8478223

Claim:
A radio frequency signal receiving structure, comprising: a waveguide component for receiving signals having at least a first frequency range and a second frequency range; a first transmission line for carrying signals within said second frequency range in a first plane; a second transmission line for carrying signals within said first frequency range in a second plane parallel to said first plane; a signal splitting component comprising: first circuitry associated with said first transmission line for producing a substantially low impedance at said first frequency range; and second circuitry associated with said second transmission line for producing a substantially low impedance at said second frequency range; wherein said first circuitry is in said first plane and said second circuitry is in said second plane; and a transition component for transferring said signals between said waveguide component and said first and second transmission lines; wherein said signal receiving structure is configured to transfer signals within said first frequency range through said second transmission line with substantially low loss and substantially high impedance matching, and to transfer signals within said second frequency range through said first transmission line with substantially low loss and substantially high impedance matching.
