Abstract

A novel design of a dual‐mode resonator with double‐ring structure for a band‐pass filter is presented in this paper. Voltage/current couplings between the two rings are proposed based on a mode chart. Because each ring exhibits dual‐mode responses, they determine the range of operation; that is, the inner/outer rings depict the upper/lower frequencies of the pass band, respectively. This is an alternative approach to improve the bandwidth of the conventional dual‐mode ring resonator. Experimental results are presented and discussed. © 2003 Wiley Periodicals, Inc.

## Abstract In this article, parallel‐coupled microstrip line (PCML) with ground plane aperture is used to improve the stopband performance of a stub tuned dual mode ring resonator band‐pass filter (BPF). The PCML with ground plane structure produces a wide‐band band‐pass response, whereas the stub

## Abstract In this article, a compact dual‐mode patch resonator for band‐pass filter applications is developed. The size reduction of the studied filter is simply achieved by etching a dual‐cross slot on the patch. Studies indicate that with this arrangement, the size can be reduced to 26.7% as co

## Abstract The CPW‐fed configurations of dual‐mode ring resonator (DMRR) are introduced to improve the performance of the dual‐mode double ring resonator (DMDRR). To obtain low insertion loss (1.65 dB at TM~110~ mode and 0.91 dB at TM~210~ mode) and high out‐of‐band rejection level (−51.95 dB) and
