A novel bandpass filter (BPF) design based on vertical split-ring resonators (VSRRs) was developed for single- and dual-band applications. The filter is composed of VSRRs, transmission lines, and apertures. The characteristics of single- and dual-band BPFs using a single VSRR and dual VSRRs, respectively, were investigated. The bandpass characteristics arising from VSSR resonance can be controlled...
A circuit-electromagnetic (EM) co-design approach to predict the power handling of tunable, high-Q, substrate-integrated waveguide (SIW) bandpass filters is presented. The prediction approach is directly applied to a heavily-loaded evanescent-mode cavity filter in bandpass domain. To demonstrate the validity of the design method for structures with severe aspect ratios, a 4% second-order Butterworth,...
