Abstract

A system for recognition and/or determination of the volume of bodies or substances made of dielectric and/or conductive material within an interior of a measuring cell in the form of a container, with a conductive and/or non-conductive measuring cell wall that has a surface directed into the interior, includes an ultra broadband microwave unit, and at least one ultra-broadband antenna having at least one disk-shaped carrier substrate which has a first surface facing a first side and a second surface which is opposed to the first surface and forms an outer side of the antenna, wherein the carrier substrate is arranged and intended to replace part of the surface of the measuring cell wall directed into the interior during operation, after fastening the ultra-broadband antenna to the measuring cell, or to extend in the interior at a distance in front of the measuring cell wall, wherein the ultra-broadband antenna includes emitter elements arranged on or in the carrier substrate is set up as an electrically short antenna with an at least substantially hemispherical emission characteristic to cover a volumetric measurement field.
