摘要：
Compact dual-band bandpass filter using short stub loaded resonators is presented in this letter, the proposed resonator possesses the advantage that its center frequency of the even mode can be flexibly controlled, whereas that of the odd-mode is fixed. A dual-band filter using pseudo-interdigital is implemented with three transmission zeros. Meandering SSLR is proposed to obtain independently controlled bandwidth at each band. Two experimental examples of filters have been designed and fabricated, good agreements ore shown between the simulation and the measurement. The bandpass filters have very smaller area in comparison of previous works. (C) 2009 Wiley Periodicals. Inc.
