Abstract

A new dual‐band bandpass filter (BPF) for 2.4/5.2 GHz WLAN systems using two‐stepped impedance resonators is presented. With new properly coupled structure, this filter appears very compact and easy to be fabricated. Measured results show that this BPF has low insertion loss of 0.3 dB at 2.4 GHz and 0.7 dB at 5.2 GHz, and wide fractional bandwidths of 30% for the first band and 17% for the second band, respectively. Measured results are in good agreement with the simulated ones. © 2008 Wiley Periodicals, Inc.

## Abstract This paper presents a compact dual‐band bandpass filter (BPF) that consists of a pair of L‐shape half‐wavelength (λ/2) stepped‐impedance resonators (SIRs) and an inverted Z‐shape resonator. The latter is actually a combined structure of two λ/4 SIRs along with a magnetic coupling in bet

## 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 a

## Abstract A compact dual‐band bandpass filter (BPF) realized with stepped impedance resonators (SIR) and T‐shaped line is proposed in this article. By appropriately selecting the impedance ratio of the SIR, a passband around at 5.4 GHz can be achieved by the second harmonic frequency of the SIR.
