A new compact bandpass filter(BPF) with improved out-of-band performance is presented in this paper. The proposed BPF consists of two non-adjacent stepped impedance resonators (SIRs), which shared a common grounded via-hole. To improve the stopband characteristics, a π type capacitive circuit is introduced in the filter. The location of the transmission zeros can be controlled by adjusting the strength...
In this paper, fully monolithic tunable millimeter-wave filters with taped-line feedings are proposed using the CPW-based periodic structures with novel multiple-contact MEMS switches. Millimeter-wave band-pass were designed, fabricated, and tested. The cascaded CPW-based periodic structures, with band-pass intrinsic filtering characteristics, are reconfigured into a self-similar single unit cell...
