Abstract
Introduction. In this paper a novel configuration of wideband coherent coaxial OMT is presented. General Design of an Orthomode Transducer. The OMT consists of elements of 3 main types: a turnstile junction between coaxial quad-ridged waveguide and 4 coaxial transmission lines; 4 right-angle coaxial junctions for each polarization; 2 antiphase power combiners/dividers. A Turnstile Junction Optimization. The optimization of a turnstile junction has been performed. Its minimized reflection coefficient is less than −28 dB in the operation frequency band 3.4–5.4 GHz. An Optimized Right-Angle Coaxial Junction. A right-angle coaxial junction has been optimized to provide reflection coefficient, which is less than −42 dB in the operation frequency band 3.4–5.4 GHz. An Antiphase Power Combiner/Divider. The optimization of an antiphase power com-biner/divider has been performed. Its minimized reflection coefficient is less than −38 dB. Conclusions. A wideband coaxial orthomode transducer has been developed for the operation frequency band 3.4–5.4 GHz. In this frequency band the reflection coefficient is less than −27 dB.
