Abstract
A mode converter for a level radar includes an input line introducing a high-frequency signal into the mode converter; a helix structure into which a conductor of the input line projects and which includes a plurality of helical electrical conductors; and a waveguide which encloses the helix structure. The helix structure is configured to convert the high-frequency signal from the input line into an H01 mode in the waveguide.

A mode converter for a level radar, comprising:
- an input line introducing a high-frequency signal into the mode converter;
- a helix structure into which a conductor of the input line projects, the helix structure including a plurality of helical electrical conductors, wherein the conductor is an internal conductor of a coaxial cable;
- and
- a waveguide enclosing the helix structure;
- wherein the helix structure is configured to convert the high-frequency signal from the input line into an H01 mode in the waveguide.
A converter body for a mode converter, comprising:
- a helix structure including a plurality of helical electrical conductors;
- a dielectric body including a cylindrical portion which is enclosed by the helix structure;
- and
- a socket in the cylindrical portion and receiving an internal conductor of a coaxial cable.
A method for manufacturing a converter body, comprising the steps of:
- providing a carrier body;
- and
- applying a helix structure to the carrier body by metallizing a plurality of helical strips on the outside of the carrier body.
