MULTI-MODE SIGNAL SOURCE

摘要

A multimode radiation source is disclosed. One embodiment includes a waveguide radiator and an orthomode transducer coupled to the waveguide radiator to provide a first signal to the waveguide radiator. The waveguide radiator is configured to receive the first signal and to radiate the first signal at a first location as a first spherical wave signal with a first phase center. The multimode source also includes transmission medium coupled to the waveguide radiator and configured to radiate a second signal and a third signal from the first location as a second spherical wave and a third spherical wave with substantially the first phase center.

1. A multimode radiation source, comprising:
a waveguide radiator having a first feed port for receiving a first signal having a first frequency and a first wavelength and for providing the first signal to the waveguide radiator so that the waveguide radiator radiates the first signal at a first location as a first spherical wave with a first phase center; a first transmission medium configured to be coupled to a first source and that is coupled to the first feed port of the waveguide radiator, the first transmission medium configured to receive the first signal and to provide the first signal to the first feed port of the waveguide radiator; a second transmission medium configured to be coupled to a second source and that is configured to provide a second signal having a second frequency and a second wavelength to the waveguide radiator so that the waveguide radiator radiates the second signal from substantially the first location as a second spherical wave with substantially the first phase center; and the second transmission medium further configured to be coupled to a third source and that is configured to provide a third signal having a third frequency and a third wavelength to the waveguide radiator so that the waveguide radiator radiates the third signal from substantially the first location as a third spherical wave with substantially the first phase center.
