Abstract

This letter presents a compact triple‐band bandpass filter using pseudointerdigital trisection stepped impedance resonators (SIR). By tuning the impedance ratio and physical length of trisection SIRs, the BPF has good triple‐band performances at 1.57‐/2.45‐/5.25‐GHz and high isolation among the three passbands. It is shown that the triple‐band bandpass filter has a small size in comparison of previous works. Good agreement is shown between the simulated and measured results. © 2008 Wiley Periodicals, Inc.

## Abstract We propose a compact dual band bandpass filter (BPF) using trisection stepped impedance resonators (SIRs). By appropriately selecting the impedance ratio (K) and length ratio (α) of the SIR, the harmonic frequencies can be tuned for generating the dual‐passband response. The BPF has goo
