| Popis: | The modified configurations of maximally flat parallel-coupled lines (MF-PCL) structure are introduced to improve the performance of the conventional MF-PCL resonator. To obtain a higher rejection (−39 dB), symmetry response, wider band (BW about 32%), and less insertion loss (−0.4 dB) filters at central frequency 5.78 GHz, the modified MF-PCL resonators by using enhanced coupling techniques are proposed herein. The size reduction of 50% is achieved. Results including surface current distributions and frequency responses are presented and discussed. © 2008 Wiley Periodicals, Inc.
