Wide-band microwave signal coupler |
摘要 |
A microwave coupler for coupling microwave energy from a first waveguide to a second waveguide disposed side by side along a propagation length includes a common coupling means, and specifically, orifices along the propagation length wherein the coupling orifices are sized to promote coupling of a favored field mode of electromagnetic energy according to a Bessel function distribution of energy along the length of the waveguide. The Bessel function distribution provides for wideband, low-loss coupling of the favored field mode and maximal isolation from non-favored field modes. The invention is particularly useful for extracting a type TE21 circular mode signal from a signal containing TE11 and TE21 circular modes wherein the TE21 mode signals are used for generating elevational and azimuthal tracking signals.
