ABSTRACT:
A ring resonator device comprises a dielectric substrate, a back-grounded conductor attached to the dielectric substrate therebeneath, a ring-shaped conductor strip, provided on the dielectric substrate, for forming an inductance element, and a capacitive element unit provided on the dielectric substrate, for forming a capacitance element. The capacitive element unit includes a plurality of capacitive elements and the capacitive elements are arranged in a distributed way so as to be laid across both opposed sides of the ring-shaped conductor strip.
