ABSTRACT:
The invention relates to a dielectric resonator (3) comprising two cylindrical discs made of a dielectric material. In the invention, the discs (3A,3B) are positioned with their planar surfaces against each other, so that they are radially displaceable with respect to each other for varying the shape of the resonator (3) and for adjusting the resonance frequency (3).
