摘要
基于集成无源器件(Integrated Passive Device,IPD)技术,研制了一款工作于毫米波频段的基片集成波导(Substrate Integrated Waveguide,SIW)带通滤波器。在SIW顶层金属上加载2个对称的并联互补开口谐振环(Complementary Split-Ring Resonator,CSRR),为带通滤波器提供了良好的带外抑制效果。测试结果表明,研制的带通滤波器在3dB频带(35.8~56.6 GHz)范围内的最低插入损耗为1.07 dB,回波损耗在38.1~55.8 GHz频带内小于-10 dB,带外抑制在65.5 GHz频点达到-33.6 dB。
By using integrated passive device(IPD)technology,a millimeter wave substrate integrated waveguide(SIW)bandpass filter is developed in this paper.Two symmetrical complementary split-ring resonator(CSRR)are loaded on the top metal of SIW,which provide a good out of band suppression effect for the band-pass filter.The measurement results show that the minimum insertion loss of the developed bandpass filter is 1.07 dB over 3dB frequency band(35.8~56.6 GHz),the return loss is less than-10 dB which ranges from 38.1~55.8 GHz,the minimum out of band rejection is-33.6 dB at the 65.5 GHz.
