1. A dielectric resonator comprising:

  • first conductor means, for operating as an inner conductor of the dielectric resonator;

    second conductor means, spaced away from the first conductor means, for operating as an outer conductor of the dielectric resonator;

    dielectric means filling the space between the first and second conductor means, for forming a resonator body having at least one open end, cooperating with the first and second conductor means; and

    third conductor means, disposed near the open end of the resonator body and electrically connected to the second conductor means, wherein a distance between the open end and at least a part of the third conductor means is adjustable to adjust a resonant frequency of the dielectric resonator.
