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. © 2002 Wiley Periodicals, Inc.
