For more size reduction of the high temperature superconducting coplanar waveguide (CPW) bandpass filter (BPF), we introduce the design method of the meanderline quarter-wavelength resonator BPF. The admittance and impedance inverters (J- and K-inverters) are realized by using interdigital gaps and meanderline short stubs. Also, we estimate the slope parameter of the meanderline resonator by using EM-simulator. In order to control the attenuation poles, we adjust the meanderline intervals and shapes of the cross-coupling section, so that we can design the frequency and number of the attenuation poles. The size of the 6-pole CPW quarter-wavelength resonator with two attenuation poles (center frequency = 2 GHz) was 3.5 × 8 mm.
