Abstract:
A dielectric resonator comprising:walls delimiting a cavity, input and output means mounted on said cavity, at least one dielectric resonator body located inside said cavity, being adjustable within a frequency range, said dielectric resonator body includes at least two dielectric resonant elements, a resonance frequency is adjustable by altering the resonant shape of the resonator body, said resonant shape of the resonator body is adjustable by a movement of at least a first resonant element of said resonator body in relation to at least a second resonant element of said resonator body, said movement is performed by rotation of at least the first element around an axis, said elements being in contact with each other, and a distance between a surface of the first resonant element facing a surface of the second resonant element, except in the area where the elements are in contact, is changed when said resonant shape of the resonator body is adjusted.
