Computer Aided Design of Non-Symmetric Six-Port Branch-Waveguide Directional Couplers

The Generalized Scattering Matrix of the Generalized 2-port discontinuity concept has been employed to develope a CAD package of non-symmetric six-port branch-waveguide couplers. The developed CAD has been succesfully applied to the design of HISPASAT's Power Divider Networks. The proposed couplers yields a more compact design.
