Compact tri-band BPF based on embeded asymmetric T-shape stub-loaded resonators

摘要：

　　In this article,a compact tri-band bandpass filter(BPF)is proposed by using T-shape asymmetrical stubloaded resonators(ASLRs).The resonator,which consists of a main transmission line and T-shape-loaded stub is utilized to obtain two frequencies at 2.48 GHz and 4.48 GHz.Then,embedding into the sides of coupled-line a symmetrical to produce a passband at 3.58 GHz,so that a tri-band BPF is successfully designed.The fabricated tri-band BPF have compact sizes of 32 mm x 28 mm.In addition,good in-band return loss,and wide passband can be also observed.Good agreement is shown between the simulated and measured results.
