Claim 20:
21. A waveguide assembly comprising:
a first waveguide;
a second waveguide that is embodied as a dielectric multi-mode waveguide; and
a waveguide transition for transmitting an electromagnetic wave between the first waveguide and the second waveguide, the waveguide transition having a dielectric waveguide piece between the first waveguide and the second waveguide; and wherein
the dielectric waveguide piece is embodied to run a lesser number of modes, at least in a front section that is facing the first waveguide, than the number of modes that may be run in the second waveguide, and wherein

in order to reduce the excitation of higher modes in the transition from the first waveguide to the second waveguide, and to enable a multi-mode transmission in the second waveguide without modal dispersion,
the front section of the dielectric waveguide piece has a reduced cross-section with respect to the second waveguide;
the front section of the dielectric waveguide has a reduced permittivity of a dielectric core material with respect to the second waveguide, and/or
the front section of the dielectric waveguide piece has an increased permittivity of a sheath, which encases the dielectric core material, with respect to the second waveguide.
