Summary:
Presented is a resonator of hybrid structure with two independently controllable frequencies of resonance. The hybrid resonator consists of a half-wavelength stripline resonator which is short-circuited at its both ends and a quarter-wavelength coplanar waveguide resonator nested in the half-wavelength resonator. Numerical analysis with a computational tool for electromagnetic fields clarifies such characteristics of dual-frequency resonance as resonant frequencies depending upon structural parameters and distributions of surface cur rent density at resonance. A typical model is fabricated and its frequency characteristics of resonance a re measured. Presented and investigated a lso is a dual-band comb-line filter consisting of hybrid resonators with stepped-impedance structure introduced.
