Dielectric waveguide and a method of manufacturing a dielectric waveguide

摘要

The present invention provides a method of efficiently manufacturing a dielectric waveguide with high reliability and precision. In the method, a resist material is formed on the outer surface of a green compact provided with a removal inhibiting layer, and predetermined portion of the green compact defined by the resist material is removed by the sand blasting method using the resist material as a mask, until the removal inhibiting layer is exposed to obtain a shaped green compact structure. The thus-obtained structure is fired to obtain a sintered body which comprises a dielectric strip and a wing.
