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 wider band (BW 13.09% at TM~110~ and 16.14% at TM~210~ mode) filters, using voltage‐couples and dual‐mode perturbations are proposed here. Simulation results including surface current distributions and frequency responses are presented and discussed. © 2007 Wiley Periodicals, Inc.

## 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
