PURPOSE:To simplify the fine adjustment of a position of a dielectric resonator by forming a supporting board of the resonator like a polygonal cylinder and forming fine grooves on the periphery of the polygonal cylinder in parallel with its axis. CONSTITUTION:The supporting board 14 of the resonator 11 is formed like a polygonal cylinder having a short axis and the fine grooves 26 parallel with the axis are formed on the outer periphery of the polygonal cylinder. The resonator 11 is fixed on the supporting board 14 so that one point on the periphery of the resonator 11 coincides with one side of the supporting board 14 and the center 31 of the resonator 11 is made eccentric from the center 32 of the supporting board 14. The interval between a coupling strip line 12 and the resonator 13 is easily set up to a required size by rotating the supporting board 14 every 45 deg.. |
