Abstract

A novel slow-wave half-wavelength coplanar waveguide (CPW) resonator using high-T-c. superconducting (HTS),films has been studied and used in a new filter topology. The slow-wave effect is achieved by the capacitively loaded structure with a symmetrical interdigital line loaded on both sides of the central line. The velocity reduction (V-p/c(0)) of the resonator is about 0.050. A three-pole Butterworth bandpass filter has been designed and fabricated with the use of the resonator (C) 2002 Wiley Periodicals, Inc.
