Waveguide coupling, high-frequency module, filling level radar, and use

摘要

A waveguide coupling includes a planar radiator element which couples the transmission signal into a waveguide of the waveguide coupling. The waveguide widens in the direction of the planar radiator element, in such a way that the radiator element can be of a comparatively large diameter without the inner walling of the waveguide detracting significantly from the signal quality.
