- Two novel dual-band microstrip filters using g/2 Stepped-Impedance-Resonator(SIR) resonators are proposed in this paper. The prominent feature of the SIR filter is that the spurious response can be controlled by the impedance ratio Rz and the length ratio of the resonator. Simulated results show that the prototype of the dual-band filter1 achieves insertion loss of 0.4dB and 0.5dB, return loss of 23dB and 23.7dB, and fractional bandwidth of 9.8%and 8.2% at 2.4GHz and 5.2GHz, respectively. And the filter2 achieves insertion loss of 1.6dB and 2.8dB, and fractional bandwidth of 6.2% and 5.1% at 2.4GHz and 5.2GHz, respectively, and the isolation between two passband is well. The proposed dual-band band pass filters are designed and fabricated. A good agreement is achieved between measured and simulated results.
