Abstract
A high-order dual-band bandpass filter using novel combined stub-loaded resonators (CSLRs) is presented in this paper. The key merits of the filter configuration are that the center frequency and also the bandwidth of each passband can be controlled conveniently. Moreover, it can build the high-order dual-band bandpass filters using the proposed resonators because of the sufficient coupling through the four symmetric stubs. A fifth-order dual-band bandpass filter designed at 2.5/3.5 GHz was built and tested. The measurement and simulation results agree very well, demonstrating the validity of the method.
