| Abstract | Optimum stepped transformers from rectangular wavegnide to ridged and all-ruetat finned waveguides are designed with the method of field expansion into eigenmodes, which inclirdes bigher order mode interaction between the step discontinuities. Computer-optimized design data are given for a Ku-band ridged waveguide prototype with a ridge width of 1 mm, as well as for Ku-band and E-band finned wavegnide transformers with commerciatfy available metaf fin thicknesses of 0.19 mm and 0.1 mm, respectively, snitable for metaf-etchirrg manufacturing techniqne. The optimum designs achieve a minimum return loss of abont 36 dB, or 34 dB for the whole Kuor E-band, respectively. The theory is verified by comparison with measured resntts. |
