Abstract
A waveguide coupling device for a radar sensor is provided, including: a waveguide configured to emit a radar signal via a radiating end of the waveguide; and a fin part with at least one excitation fin, via which a radio frequency (RF) signal can be coupled into the waveguide for generating the radar signal, the waveguide and the fin part being formed in two parts, and the fin part being mechanically coupled to an excitation end of the waveguide opposite the radiating end of the waveguide.

A waveguide coupling device for a radar sensor, comprising:
- a waveguide configured to emit a radar signal via a radiating end of the waveguide;
- and
- a fin part, via which a radio frequency (RF) signal is configured to be coupled into the waveguide for generating the radar signal,
- wherein the waveguide and the fin part are formed in two parts,
- wherein the fin part is mechanically coupled to an excitation end of the waveguide opposite the radiating end of the waveguide,
- wherein the fin part has at least two excitation fins configured to be excited by the RF signal to form at least two resonant waves having mutually different resonant frequencies, and
- wherein the waveguide is further configured to generate the radar signal based on a superposition of the at least two resonant waves in an inner volume of the waveguide.
