A novel and compact bandpass filter (BPF) using meandered microstrip/coplanar waveguide (CPW) hybrid structures paralleled with a pair of open-ended stepped impedance resonators (SIRs) is proposed. The distinct filtering characteristics of this new classification of transmission line filter are investigated theoretically and experimentally. At the bottom of substrate material, the two identical CPW short circuited resonators and an open-circuited resonator are broadside-coupled to the top microstrip main transmission line, respectively. To reduce the area of the filter, the folded microstrip/CPW composite structures and the microstrip open circuited SIRs have been applied to layout. A demonstrator with approximately 4.6 % fractional bandwidth (FBW) at the center frequency 6 .45 GHz is designed. The developed filter is successfully realized in theory and verified by the full-wave electromagnetic (EM) simulation and the experiment. The obtained frequency responses demonstrated the filter with an excellent band-pass property. Measured results are in good agreement with the electromagnetic simulation results.

“…For applying to HTS transmit tunable filters, we have been studying the feasibility of HTS disk resonators tuned by moving an upper dielectric plate which is actuated by a piezo-motor [5]. In general, microstrip dual-mode disk filters are attractive for increasing power handling capability and compactness [6,7]. We present the improved power properties such as higher power handling capability and lower intermodulation distortion using an upper dielectric plate with an upper conducting plate for dual-mode on HTS disk resonator filters [8,9].…”

“…In general, microstrip BPFs may be designed using single-or dualmode resonators. Dual-mode microstrip resonators are attractive because each of them can be used as a doubly tuned resonant circuit and hence, the number of resonators required for a given degree filter is reduced by half, which results in a compact filter topology [1][2][3][4][5][6][7][8][9][10][11][12][13].…”

“…Its operation consists of two degenerate modes, which are excited by asymmetric feed-lines and by the addition of notches or stubs on the ring or patch resonators [2][3][4][5][6][7][8][9][10][11]. Recently, interests in dual-mode for design of low-cost, high-performance BPFs have grown.…”

Based on the geometry relationship of the conventional dual‐mode ring resonators, this study concisely describes the operation principle of a kind of dual‐mode resonator filters with in‐line feed‐lines. The investigated filter topology is fed by two pairs of orthogonal branch lines and can realize in‐line configuration for the input and output (I/O) ports, which is useful in many practical applications. Meanwhile, the influences of feed‐lines on transmission‐zeros (TZs) are, for the first time, investigated to guide the design of this kind of filters. Several demonstrators are designed and examined, and good results are obtained. © 2006 Wiley Periodicals, Inc.
