| 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×86 mm×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。 |

| Abstract: |
| 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 feeded using T-cap. The measured and simulated results are also given. The filter which only sizes 140 mm×86 mm×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 successfully applied in many projects. |
