Abstract

A novel microstrip bandpass filter using a dual‐mode square‐ring resonator is presented in this paper, in which the input/output microstrip lines are arranged under the square‐ring to improve the coupling between the microstrip lines and the square‐ring. The filter has been investigated numerically and experimentally. The measured result shows that the filter has a minimum insertion loss of 1.5 dB inside its passband and the out‐of‐band rejection level of below −26 dB. © 2006 Wiley Periodicals, Inc.

## 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
