The invention relates to a waveguide arrangement for guiding electromagnetic waves, which comprises a rectangular waveguide and a circular waveguide. The rectangular waveguide merges into the circular waveguide at an angle. The circular waveguide is filled with a dielectric which projects into the rectangular waveguide in a transition section. The dielectric filling is beveled at a defined angle in the transition section so that a transition surface is formed by the inner edge at the transition of the waveguide arrangement and the end face of the rectangular waveguide at the transition. The dielectric filling is preferably flush with the closing wall of the rectangular waveguide.

The present invention features a waveguide transition. A waveguide transition is used to join two dissimilar segments of waveguide, in this case coplanar waveguide to rectangular waveguide, and vice-versa. Care taken during the design of the waveguide transition ensures that the reflection of electromagnetic waves, which may be traveling along the coplanar waveguide segment and toward the waveguide transition and subsequent rectangular waveguide segment, is minimized.
