Abstract
The invention relates to an apparatus for transmitting and receiving electromagnetic waves (EM waves) for ascertaining and monitoring a fill level of a medium in a container, comprising a first hollow conductor with a first coupling element for the out- and in-coupling of EM waves, a second hollow conductor with a second coupling element for the out- and in-coupling of EM waves, a horn radiator for radiating and focusing of EM waves, wherein the first and second hollow conductors are dimensioned such that EM waves out-coupled from the first and second coupling elements radiate from the horn radiator scattered and with weak intensity, or scattered and weak intensity EM waves, which are received from the horn radiator, couple to the first and second coupling elements, and EM waves out-coupled only from the first coupling element radiate from the horn radiator focused and with strong intensity, or focused and strong intensity EM waves, which are received from the horn radiator couple only to the first coupling element.
