This filter is fabricated and its photographs are presented in Figure 6. Simulated and measured frequency responses are compared in Figure 6. The overall size for the proposed BPF is about 16 Â 16 mm 2 (0.17 kg Â 0.17 kg, kg is the guided wavelength). Results show that the two passbands are centered at 1.83 and 2.45 GHz with the fractional bandwith of 5.5 and 4.1%, respectively. The minimum insertion losses in the two passbands are 2.3 and 1.8 dB, respectively. The return losses within the passbands are better than À15 dB. There are four transmission zeros on both sides of the passbands. They are À56, À49, À48, and À40 dB at frequencies of 1.66, 2.10, 2.31, and 2.65, respectively. They are close to the passband edges and can greatly improve the selectivity and stopband suppression of the proposed filter. Measured results agree well with the simulated ones. CONCLUSIONSA compact dual-band microstrip BPF with independently controlled center frequencies is introduced in this letter. It consists of meander short-circuit quarter-wavelength resonators for compactness. Its equivalent circuit model is explained and the parameters are extracted effectively. This filter is compact, simple, and attractive for dual-band wireless communication applications. ACKNOWLEDGMENTS
