Abstract:
1. A discrete cavity resonator consisting essentially of: a single cavity dielectric base comprising a dielectric material having a dielectric constant, said dielectric base having a width, a length greater than or equal to said width defined between a first end edge and an opposed second end edge of said dielectric base, a thickness and an outer surface defining first and second opposed major surfaces, peripheral side surfaces and first and second opposed end surfaces of said dielectric base; at least one metal contact having a predetermined area disposed in a predetermined location only on one of said first and said second major surfaces of said dielectric base to provide a predetermined loaded Q for said resonator, said metal contact being capacitively coupled to said single cavity of said dielectric base; a metal ground coating entirely covering said outer surface of said dielectric base with the exception of said at least one metal contact and at least one isolation region formed on said one of said first and said second major surfaces which is free of said metal ground coating, said at least one isolation region surrounding said at least one metal contact and having an area sufficient to prevent significant coupling between said at least one metal contact and said metal ground coating; wherein said dielectric constant, said width and said length of said dielectric base are each selected such that said discrete resonator resonates at least at one predetermined resonant frequency in a GHz frequency range.
