Abstract

A parallel coupled‐line microstrip filter is designed and implemented on PCB with its maximum bandwidth. In this paper, this filter has presented almost very good characteristics including the simulated bandwidth of 67%, the measured bandwidth of 64%, lower insertion loss of 1.27 dB, and flat response in the pass‐band. The maximum bandwidth fabricated on PCB shows good agreement with the theoretically calculated bandwidth of 70% due to the narrower gap size between the coupled lines. © 2005 Wiley Periodicals, Inc.

## Abstract A wideband bandpass filter using parallel‐coupled‐lines with periodical grooves is presented in this article. Owing to the slow wave effect brought by periodical grooves, the proposed structure's resonant frequency can be lowered effectively. This effect has been used in this article to
