PCT No. PCT/FI95/00544 Sec. 371 Date Jun. 4, 1996 Sec. 102(e) Date Jun. 4, 1996 PCT Filed Oct. 4, 1995 PCT Pub. No. WO96/11508 PCT Pub. Date Apr. 18, 1996A dielectric resonator including a dielectric cylindrical resonator disc, and a resonance frequency controller. The frequency controller includes a dielectric cylindrical adjustment disc provided on the resonator disc so that the adjustment disc is movable in the radial direction for controlling the resonance frequency of the resonator. The frequency controller further includes a dielectric fine adjustment disc, provided on the adjustment disc so that the fine adjustment disc is movable by a movement of an adjustment mechanism with respect to the adjustment disc for fine adjustment of the resonance frequency. Thus, the frequency controller has two slopes of adjustment, whereby the adjustment is fast due to the movement of both adjustment discs, and also extremely accurate due to the fine adjustment function, which is achieved when the thinner adjustment disc alone is moved.
