Research output: Contribution to journalArticlepeer-review


Two novel fifth order, 2.5-GHz bandpass filters, with 4% bandwidths were designed and fabricated. The filters which are modified versions of the hairpin filter are designed empirically using the optimization feature in microwave simulation software. We found good agreement between the simulated and measured responses of these filters, validating the optimization design methodology. The original hairpin filter has also been fabricated, and it is shown that the novel filters have good performance in comparison. (c) 2008 Wiley Periodicals, Inc.
