Abstract
A frequency-tunable microwave-frequency wave filter with dielectric resonator, comprises a metallic cavity and at least one stack along a rotation axis, the resonator-forming stack being disposed inside the cavity and comprising at least a first and a second element each made of dielectric material, the second element being mobile in rotation with respect to the first element around the rotation axis and exhibiting a first position and at least one second position separated by an angle of rotation, and the elements exhibiting shapes such that the overall geometry of the stack is different in the at least two positions, the stack forming a first resonator adapted so that the filter exhibits a first central frequency when the second element is in the first position, and forming a second resonator adapted so that the filter exhibits a second central frequency when the second element is in the second position.
