摘　　要：基于切比雪夫带通滤波器原型分析,设计了一款工作频率在55.5~63.1 GHz基片集成波导(Substrate Integrated Waveguide,SIW)带通滤波器(Bandpass Filter,BPF)。加载2组互补开口谐振环(Complimentary Split Resonant Ring,CSRR),采用其带阻特性在带外产生传输零点,获得了更好的带外抑制效果,改善了滤波器的矩形系数。采用集成无源器件(Integrated Passive Device,IPD)工艺加工了设计的带通滤波器,实测结果表明,滤波器通带内最小插入损耗(Insertion Loss,IL)为-2.7 dB,通带内回波损耗(Return Loss,RL)小于-16.3 dB,面积为3.4 mm×1.4 mm。Based on the analysis of the Chebyshev bandpass filter prototype,a 55.5~63.1 GHz Substrate Integrated Waveguide(SIW)band-pass filter(BPF)is presented in this paper.This BPF employs two pairs of complementary split resonant rings(CSRR)to generate the transmission zero.Thus,both the out-of-band suppression and the rectangular coefficient of the filter are improved.The proposed BPF is fabricated in a Integrated Passive Device(IPD)process.The measurement results show that the minimum insertion loss(IL)is 2.7 dB,the return loss(RL)is less than 16.3 dB in the operating frequency range,and the filter area size is 3.4 mm×1.4 mm.
