Abstract
A compact feed system () is provided which comprises an orthomode transducer or junction () and a waveguide H-plane directional coupler (). The waveguide H-plane directional coupler may comprise two hollow waveguide sections () and a coupling section () 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 () formed at an inner side of the waveguide H-plane directional coupler. The orthomode transducer or junction () may be positioned at least partially in the recess to increase compactness of the feed system.
