Compact feed system with developable waveguide H-plane directional coupler

Abstract

A compact feed system (600) is provided which comprises an orthomode transducer or junction (400) and a waveguide H-plane directional coupler (100). The waveguide H-plane directional coupler may comprise two hollow waveguide sections (110, 120) and a coupling section (130) arranged in between the two hollow waveguide sections for coupling a signal from one hollow waveguide section to another hollow waveguide section. In a transverse cross-section of the waveguide H-plane directional coupler, the hollow waveguide sections may be angled towards the coupling section and delimit a recess (20) formed at an inner side of the waveguide H-plane directional coupler. The orthomode transducer or junction (400) may be positioned at least partially in the recess to increase compactness of the feed system.
