摘要: A novel tri-band bandpass filter (BPF) based on ring multi-mode resonator (R-MMR) is proposed in this paper. The consists of an R-MMR and a pair parallel coupled lines. Because the symmetrical, its resonant characteristics can be analyzed by using odd- even-mode analysis method. When couple stubs are loaded resonator, six transmission poles four zeros created, BPF realized employing To miniaturize size, folded. prototype designed, fabricated measured. Good agreement obtained between simulated measured results.
