Abstract

A sensor for liquid and/or gas analysis comprising a measuring transducer for producing a measurement signal, and, connected with the measuring transducer, especially separably, a compact transmitter, which is embodied for receiving and further processing the measurement signal. The compact transmitter includes: a transmitter housing; a transmitter circuit arranged in the transmitter housing; arranged in the transmitter housing, a first interface, via which the transmitter circuit is connectable by means of a connection cable with a first superordinated data processing system, especially one embodied as a superordinated control system; and arranged in the transmitter housing, a second interface, which connects the transmitter circuit with an antenna and which is embodied to supply the antenna with, or to receive by means of the antenna, a radio signal, whose center frequency has a wavelength λ. The antenna includes a radiating element and at least one metal mirror element, and wherein the radiating element has a length of λ/8 up to 3λ/8, especially of, for instance, λ/4.
