MICROSTRIP RESONATOR, HIGH FREQUENCY COMPONENT AND MICROSTRIP RESONATOR FREQUENCY ADJUSTMENT METHOD

摘要

A microstrip resonator comprises a strip conductor (12) on the upper surface of a dielectric substrate (11) with both ends open, insular resonance frequency rough adjustment conductors (14a-14c) and resonance frequency fine adjustment conductors (15a-15c) arranged oppositely at the open ends, and a ground electrode (13) arranged on the lower surface of the dielectric substrate (11). The portion of the resonance frequency adjustment conductor is imaged through a trimming hole (32) formed in a shield case (31) covering the periphery of the dielectric substrate (11) and trimming is performed by an amount corresponding to the resonance frequency adjustment amount.
