Abstract

The present paper suggests a new type of TE₁₀-TE₂₀ mode transducer vertically excited in a way of crossing the electric fields of an over-moded waveguide (OMWG) and a single-mode one (SMWG). By optimizing a matching element the mode-conversion efficiency more than 99% is obtained over the fractional bandwidth of about 17%. The reason why such a good performance is obtained is because the present mode transducer is free from undesired mode excitation in principle. The validity of the design concept is also confirmed experimentally. Moreover, an elimination technique of unwanted resonant response is successfully demonstrated.
