A device for transmitting a signal with the aid of waveguides in rotating systems. The device includes at least one transmitting waveguide and at least one receiving waveguide. The at least one receiving waveguide and the at least one transmitting waveguide being divided into multiple radially distributed segments. The radially distributed segments of the at least one receiving waveguide each include a tap. An adder for adding the signals obtained with the aid of the taps of the radially distributed segments of the at least one receiving waveguide is also provided.
