Patent

CA 2233393

A dielectric filter is formed by constituting electrode non-formation parts opposed as inserting both main surfaces of a dielectric plate as dielectric resonator, as well as by providing two coupling members coupled to said dielectric resonator, and a large attenuation quantity required for a certain frequency in a blocking area is secured by generating an attenuation pole in a predetermined frequency area; a dielectric resonator is Constituted by providing an electrode on a upper surface of a dielectric plate as a portion thereof being an electrode non- formation part, providing an electrode on a lower surface of the dielectric plate as a portion opposite to the electrode non-formation part being an electrode non-formation part, and nearly placing probes as coupling members, as well as placing both probes in note-parallel.
