Abstract
The invention relates to a horn antenna for a radar-filling level measuring device having an antenna envelope (3) that comprises a flaring hollow space (4) of the antenna, in which a filling (10) is present at least in part filling up said hollow space (4) of the antenna, and having an encasing (10, 20) of a dielectric material and enclosing the outside of the antenna envelope (3) and closing the opening (3a) of the hollow space of the hollow space (4) of the antenna.
Claims26
A horn antenna for a radar-filling level measuring device having an antenna envelope that comprises an outside, a flaring hollow space, a filling at least in part filling up said hollow space, and having an encasing of dielectric material that encloses the outside of the antenna envelope and closes an opening of the hollow space.
The horn antenna according to any of the preceding claims, further comprising a flange at least in part coated with the dielectric material of the encasing in a radiation direction.
A horn antenna for a radar-filling level measuring device having an antenna envelope that comprises an outside, an open end, a flaring hollow space, a multipart filling of dielectric material at least in part filling up said hollow space, and a dielectric outside encasing closing the open end, covering the outside of the antenna envelope and extending radially to have a sealing effect with respect to an inner receptacle space.
A horn antenna, comprising:
- a body including a wall, an interior space, an open end;
- a dielectric filling in the interior space;
- a dielectric outer coating on an outer surface of the wall;
- and
- a dielectric closure on the open end.
