PURPOSE:To achieve adjustment after assemblt by forming a leakage radiation part, where an electromagnetic wave leaks, in the short-circuit end flank of each lambda/4 TEM coaxial dielectric resonator, and then coupling short-circuit ends with each other electromagnetically through the radiation part. CONSTITUTION:A dielecttic resonator 1 has a leakage radiation part, e.g. a groove 7 in the flank of a dielectric unit 2 on the side of a short-circuit end 1a. A short-circuit electrode is formed over the entire the flank of the short-circuit end 1a except the part of the groove 7. The shape, width, length, depth, etc., of the groove 7 are specified adequately in advance. Further, a spacer S for deciding on the degree of coupling is interposed between the short-circuit ends 1a of both the resonators 1 and 1. The degree of coupling is adjusted by varying an angle theta between the grooves 7 of the both. |
