WAVEGUIDE COUPLING HIGH FREQUENCY MODULE FILLING LEVEL RADAR AND USE

摘要

The invention relates to a waveguide coupling which has a planar emitter element which couples the transmitted signal into a waveguide of the waveguide coupling. The waveguide is expanded in the direction of the planar emitter element such that the emitter element can have a relatively large diameter without the inner wall of the waveguide significantly worsening the signal quality.
