Abstract: A discrete resonator is provided, including a dielectric base having a dielectric constant. A metal contact formed on a major surface of the dielectric base has a predetermined area and is positioned at a predetermined location on the dielectric base to provide a predetermined loaded Q for the resonator. A metal ground coating is formed on the outer surface of the dielectric base with the exception of an isolation region surrounding the metal contact that is free of the metal ground coating. The area of the isolation region is sufficient to prevent significant coupling between the metal contact and the metal ground coating. The dielectric constant of the material used for the base, and the width and length of the dielectric base are each selected such that the resonator resonates at least at one predetermined resonant frequency in the GHz frequency range.
