2.44/5.25 GHz Dual-Band Pass Filter Using l /4 Stepped-Impedance Resonators For WLAN Applications
A novel dual-band pass filter (DBPF) is accomplished using l /4 stepped impedance resonators (SIRs) with low insertion loss, covering the frequency range of both 2.40~2.48 GHz and 5.15~5.35 GHz, which are the operating frequencies of IEEE 802.11 a/g, respectively. Additionally, a new frequency transformation is applied to evolve the general design formulas of DBPF. The derived DBPF topology is then simplified with the aid of J-inverters, in which only J inverters and paralleled LC resonators corresponding to the l /4 SIRs are involved. Finally, the filter is fabricated easily using distributed elements and the measurement is in a good agreement with the simulation.
