ABSTRACT:
A dielectric resonator is arranged such that an upper electrode4aand a lower electrode4bare disposed on both surfaces of a dielectric substrate1that has an interior metallized layer inside thereof, which is formed with a resonance aperture area3. A dielectric filter is produced by arranging a plurality of rows of the dielectric resonators, and using a multilayer-type waveguide6formed by lines of via conductors for signal input and output. This dielectric filter allows the accuracy for designing resonant frequencies to be greatly improved and the production process to be simplified.
