ABSTRACT:
The present invention relates to an antenna system for a level measuring device for emitting microwaves by means of an antenna horn, at the front side of the small funnel aperture thereof. HF energy in the form of microwave signals is directly axially coupled by means of planar structures having one patch or several patches.
