摘要: A tri-band bandpass filter (BPF) using square ring short stub loaded resonators (SRSLR) is presented. The characteristics of the triple-mode resonator are investigated by even/odd mode analysis. centre frequencies first three passbands can be independently controlled tuning dimensions SRSLR. Moreover, has been implemented with eight transmission zeros to improve selectivity. prototype a BPF centred at 2.4, 3.5 and 5.2 GHz designed fabricated. Good agreement found between measured simulated results.
