A method for transmitting a signal, signal transmitting means and measuring means

In the method for transmitting a signal in the form of an ultra-short and / or decimetre and / or centimeter and / or millimeter wave (based on vacuum wavelength), preferably with a frequency or frequencies, in particular carrier frequency (s) of up to 100 GHz, the signal by means of a dielectric waveguide (20) is transmitted. The signal transmission apparatus comprises a wave source (5, 10; 5, 10, 35) for generating an ultra-short and / or decimetre and / or centimeter and / or millimeter-wave signal, preferably having a frequency or frequencies, in particular carrier frequency (s), of up to 100 GHz, a dielectric waveguide (20) and a first coupling means (15) for coupling the signal generated by the wave source into the waveguide (20). The measurement device comprises such a signal transmitting means and at least one sensor which is provided with a modulation means (10; 30; 35) and / or the first (15) and / or a second coupling device (25) and / or the wave source (5, 10; 5, 10, 35) and / or the wave receiver (30) is signal-connected.
