A waveguide system comprises a differential waveguide with at least one first and one second signal conductor, which are coupled to one another within the waveguide, and a divider network with front network elements disposed at a front end of the waveguide in the signal-flow direction and with rear network elements disposed at a rear end of the waveguide in the signal-flow direction. The front network elements comprise a first parallel element, which extends in the direction from the first signal conductor to the earth conductor, and a second parallel element, which extends in the direction from the second signal conductor to the earth conductor. Alternatively, the parallel element can also be disposed between the signal conductors.
