Abstract
A fill level measuring device includes: a transmitting and receiving system for producing a higher frequency microwave signal and a lower frequency microwave signal. The transmitting and receiving system includes a single antenna, which has an internally funnel shaped horn and two hollow conductor segments connected with one another and connected to the horn. The antenna additionally includes, a coaxial conductor connection, via which the antenna is fed with the lower frequency microwave signal and the associated lower frequency echo signal is received. The antenna additionally includes, connected to a horn-remote end of that one of the two hollow conductor segments arranged on an end of the hollow conductor segment adjoining the horn, a hollow conductor connection, via which the antenna is fed with the higher frequency microwave signal and the associated higher frequency echo signal is received.
