The present invention is related to a device for generating waveguide modes for use in a feed horn of a satellite antenna system, said waveguide modes comprising at least one excitation mode of higher order than the fundamental mode, said device comprising a waveguide containing a first waveguide section with at least three longitudinal slots extending in the inner side of said waveguide, characterized in that said waveguide contains a second waveguide section with at least three longitudinal slots extending in said inner side of said waveguide.

Mode generator device for a satellite antenna system and method for producing the same

A multi-band transducer is described incorporating a coaxial waveguide interface for use with a multi-band feed and incorporating bent shaped probes yielding all-planar interfaces in microstrip for all frequency ranges and suitable for mass production. Hybrids can be incorporated for linear or circular polarization applications.
