Abstract
For fixing a dielectric insert in a waveguide, clamping bodies are provided which contact the dielectric insert on its outer periphery only tangentially. The dielectric insert is fixed in a wave propagation direction by a supporting element. In a further embodiment, the dielectric insert is rigidly mounted on the supporting element. As a result thermal stresses can be absorbed.
