Abstract

A slot‐type split‐ring resonator (SRR) as a new type of perturbation element for dual‐mode square patch resonator is introduced in this article.The slot‐type SRR used in the patch resonator allows coupling between the two degenerate modes. Moreover, coupling characteristics can be adjusted by the location of slot‐type SRR. By adding two notches in the dual‐mode filter with slot‐type SRR, the high degenerate mode near the passband is eliminated, and the center frequency is lowered slightly. It has been verified by both simulation and measurement. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett, 2011; View this article online at wileyonlinelibrary.com. DOI 10.1002/mop.26148

## Abstract We proposed a novel dual‐mode dual band bandpass filter (BPF) operating at 2.4/5.7 GHz by using a right cross‐slotted patch resonator (RCSPR) combined with a pair of square etched areas (SEAs). A pair of right crossed slot embedded in the center of the patch resonator is used to tune th

## Abstract A novel bandpass filter using a dual‐mode square‐patch resonator is proposed in this article. The input and the output of the filter are constructed on a coplanar‐waveguide (CPW) and a microstrip line, respectively. Therefore, a transition of CPW/microstrip may be simultaneously realize
