| Abstract(in English) | Design and performance of miniaturized coplanar waveguide (CPW) bandpass filters (BPFs) using high T_c superconducting (HTS) films have been studied. In order to realize the miniaturized filters, we coupled highly packed meanderline half-wavelength resonators with interdigital gaps. We propose two design methods. (1) We measured admittance inverters (J inverters) and susceptance slope parameters (b). (2) We measured external Q (Q_e) and coupling constant (k). These parameters are calculated from the cascade matrix (K-matrix) and scattering matrix (S-matrix) obtained by the 2.5-dimensional electromagnetic field simulator (HP-Momentum). It is shown that the size of the filters can be greatly reduced by introducing CPW with highly packed meanderline geometry (center frequency 2GHz, fractional band width 15MHz, ripple 0.1dB) packed within 10mm square substrate. |
