摘要：
A high selective stepped-impedance dual-band bandpass filter is presented. The filter has a feature of two tunable passbands over a wide frequency range and compact size. A multi-coupling scheme is introduced so that two finite transmission zeros are generated between the two passbands to achieve a high out-of-band rejection. (C) 2006 Wiley Periodicals, Inc.
