Abstract

In this paper, new microstrip cross-coupled elliptic function (CCEF) bandpass filters (BPFs) using folded split-ring resonators (FSRR) are proposed. The CCEF BPFs using these resonators are designed with maintaining a good filter performance and reducing the size significantly. The four-pole and three-pole CCEF BPFs show a 3-dB bandwidth of 3.0% at the center frequency of 2.0 GHz, and insertion losses of 4.28 and 2.77 dB, respectively. © 2006 Wiley Periodicals, Inc.
