摘要: This letter presents a novel dual-band bandpass filter with controllable frequencies and bandwidths as well high out-of-band rejection level. The proposed utilizes stub-loaded quad-mode resonator. Every two modes, which can be flexibly controlled, are utilized to form passband frequency bandwidth. Source-load coupling hook-shape feed lines introduced selectivity is achieved. An experimental implemented the results presented for validation.
