초록

A compact dual-band bandpass filter using side-coupled octagonal split-ring resonators (SRR) is introduced in this letter. The proposed filter employs two sets of SRRs operating at different frequencies to generate two passbands. Besides, the side-coupled stubs provide sufficient degrees of freedom to control the bandwidth of the two passbands. Four transmission zeros can be created close to passband edges which leads to high skirt selectivity. Measured results are in good agreement with the EM simulation results. The circuit size of the proposed filter occupies only 22.4 x 12.6 mm(2) (approximate to 0.25 x 0.14 lambda(g)). (C) 2011 Wiley Periodicals, Inc.
