摘要
提出了一种利用HFSS和Designer协同仿真快速设计双频滤波器的方法。两路滤波器都由同轴腔体带通滤波器组成,采用T型抽头的馈电方式,通过灵活的布局来减小滤波器的体积,最终加工了实物,给出了仿真和实测结果。该滤波器的工作频带覆盖1.421~1.858 GHz,并使得1.576~1.604 GHz频段的抑制在30 dB以上,整体尺寸仅为140 mm＆#215;86 mm＆#215;45 mm,满足了机载环境的使用。目前,该滤波器已应用于多个工程。
This paper presents a dual-passband filter using the method of co-simulation design with HFSS and Designer. Both of passband filters with miniature size are consisted of coaxial bandpass filters and fee-ded using T-cap. The measured and simulated results are also given. The filter which only sizes 140 mm＆#237;86 mm＆#237;45 mm workes on the 1 . 421 ~ 1 . 858 GHz and restraines more than 30 dB at 1 . 576 ~1. 604 GHz,so it satisfies the application requirement in aircraft. The dual-passband filter has been suc-cessfully applied in many projects.
