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.
Claims15
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 an internal conductor of a coaxial cable of the input line projects, the helix structure including a plurality of helical electrical conductors;
- 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 method for manufacturing a mode converter, comprising the steps of:
- providing a carrier body;
- including an input line introducing a high-frequency signal into the mode converter;
- applying a metallic helix structure to the carrier body by metallizing a plurality of helical strips on the outside of the carrier body using laser direct structuring of the carrier body, the metallic helix structure shaped and sized for an internal conductor of a coaxial cable of the input line to project into the metallic helix structure, the metallic helix structure including a plurality of helical electrical conductors;
- and
- including a waveguide enclosing the metallic helix structure,
- wherein the metallic helix structure is configured to convert the high-frequency signal from the input line into an H01 mode in the waveguide.
