Dielectric resonant device dielectric filter dielectric duplexer communication apparatus including the same and method for forming input-output electrode of the dielectric resonant device

摘要

PURPOSE: A dielectric resonance device, a dielectric filter, and a dielectric duplexer are provided to obtain a dielectric resonance device having a maximum outer engaging capacity. CONSTITUTION: A dielectric resonance device comprises a dielectric block and an outer conductor. The dielectric block has a cubic shape, and has at least one inner conductor therein. The outer conductor is formed such that it is substantially perpendicular to the shaft of the inner conductor. The outer conductor is formed on the outer surface of the dielectric block. At least one inputting and outputting electrode is formed such that it makes contact with the opened surface. According to the dielectric resonance device, a dielectric resonance device having a maximum outer engaging capacity is obtained.
