Abstract
A signal coupling device associating a first frequency band signal and a second, different frequency band, signal in a common waveguide and distributing the signals to two separate waveguides. The device comprises first and second circular waveguides. The second waveguide is coaxially arranged inside a cylindrical interior of the first waveguide. The first waveguide comprises inwardly projecting inner circumference projections in a region occupied only by the first waveguide. The projections activate higher modes from a fundamental mode. The first and second waveguides and the projections cause the superposition of the fundamental and higher modes to produce a wave front having field components in the first frequency band only in a cylindrical ring region between the second waveguide outer circumference and the first waveguide inner circumference, and having field components in the second frequency band only in a cylindrical interior of the second waveguide.
