ABSTRACT:
A dielectric filter comprising a dielectric ceramic block in which two or more than two through bores are provided in parallel with each other so that they extend from a first end surface to a second end surface of the block. Each through bore has an inner surface covered with an electrically conductive layer. Auxiliary through bores are provided which extend from the associated one of the through bores to one of four lateral side surfaces of the block. Each auxiliary through bore has an inner surface covered with an electrically conductive layer and an opening at the respective one lateral side surface which is surrounded by an electrically non-conductive section. An electrically non-conductive connecting section is provided for connecting the electrically non-conductive sections, thereby providing a large bandwidth. There is also provided a method of regulating the frequency bandwidth of a dielectric filter in order to achieve a large bandwidth.
