Zusammenfassung:	A compact and efficient antenna for radiofrequency radar-based fill level measuring devices includes a mount with a media-tight cavity; an input coupling structure by means of which the radar signal is able to be coupled into the cavity along a main beam axis; and a lens that refracts the radar signal. The lens seals the cavity of the mount in such that the input coupling structure is located in the focus of the lens and the lens is aligned in the main beam axis of the input coupling structure. The mount or the lens and the input coupling structure may be constructed from two separate sub-components assembled along a defined joining seam such that the cavity is sealed in media-tight fashion and the mount or the antenna is formed.
