Abstract

A multi-band orthomode transducer device comprises a three-dimensional housing. The three-dimensional housing encompasses at least two orthomode transducers, each orthomode transducer being assigned to three ports of which a first port relates to a first polarization, a second port relates to a second polarization and a third port relates to a combination of the first and second polarizations. Each of the orthomode transducers has a waveguide connected with the three ports. The waveguides of the orthomode transducers are located in the three-dimensional housing without intersecting each other.

First claim

The invention claimed is:
