On a basis of 2 multimode resonators (MMRs) using stub‐loaded taper, a compact quint‐band BPF is proposed. Progressively, triple open‐circuited stubs and notch are loaded to taper without introducing extra coupling paths, and both tri‐, quad‐ and quint‐band BPF responses are available. In this way, design procedure is rigorous and reduction of coupling paths minimizes the quint‐band BPF design complexity, simultaneously. Meanwhile, owing to the cancelling effect of notch, independent control on central frequencies of 2 passbands can be achieved. The insertion loss is lower since taper is adopted to the building of MMR. Good agreement between simulated and measured results validates the design method.

“…Two multiband bandpass filters are reported, whereas six pairs of SIR are employed to implement sext‐band . However, a great deal of resonators in previous works are built up by SIR with or without loaded stubs, which introduces discontinuities and causes higher‐order modes or radiation loss unavoidably. Since tapered‐line has served as an important item in the application of impedance transformation, to the best of our knowledge, there are hardly any multiband designs using tapered‐line.…”

On a basis of multimode resonator (MMR) using SIRs‐loaded tapered‐line (SIRTL),novel quad‐ and sext‐band bandpass filter are investigated and fabricated. Due to some merits like existing accurate analytical technique, simplicity in construction and excellent matching behavior, parabolic tapered‐line are selected as the building block of MMR. In addition, with SIRs loaded at different points of tapered‐line, quad‐ and sext‐band responses can be obtained. Moreover, relationship between parabolic tapered‐line and profile of microstrip is set up. Accordingly, circular‐profile microstrip has been chosen to realize parabolic tapered‐line. Therefore, designs of quad‐ and sext‐band bandpass filter become available. Good agreement between simulated and measured results validates the design method.

In this article, parallel multiplexing, in‐line, and parallel resonator topologies can be selected to realize a multiple band filter. The multiband filtering functions can be synthesized with four different theories: complex load, frequency transformation, strategic optimization, and direct iterative methods. Once the polynomials in reflect and transmission coefficients are obtained, the coupling matrix for realizing the multiband filter can be obtained directly. The multiband filters with selected topology can then be realized using planar, multilayer, coaxial, and waveguide structures. Furthermore, dual‐mode and multimode resonators can be introduced for size reduction.
