<p>The invention relates to a dielectric resonator comprising a dielectric resonator disc (33), a frequency controller comprising an adjustment mechanism (31) and a dielectric adjustment plane (41), which is substantially parallel with the resonator disc (33), and movable by means of the adjustment mechanism in the perpendicular direction with respect to the resonator disc for adjusting the resonance frequency. The frequency adjuster of the invention comprises a plurality of dielectric adjustment planes (37, 38, 39, 40, 41), which are substantially installed concentrically and parallel one after another, the mechanical engagement (42) of said planes with each other and with the adjustment mechanism (31) enabling movement of the adjustment plates both with respect to the resonator disc (33) and to each other, so that the adjustment plates are arranged in layers on top of each other as the adjusting movement is proceeding. This results in improved linearity of frequency control and a longer adjustment distance, which both improve the adjustment accuracy.</p> |
