摘要

In this letter, a compact dual-band bandpass filter (BPF) using the meandering stepped impedance resonators (MSIRs) for the wireless local area networks (WLANs) is proposed. The dual-band performance of the BPF is adjusted by the physical length (α) and impedance ratio (K) of the MSIRs. The proposed BPF is designed and fabricated, showing good dual-passband responses at 2.4/5.7 GHz and a high isolation between the two passbands. The overall circuit size of the BPF is much smaller than the previous work. Good agreement with response of electromagnetic (EM) simulation and measurement is obtained.
