| 摘 要： | 设计了一款基于基片集成波导的ku波段卫星通信的带通滤波器。描述了位于SIW内部的金属通孔的等效电路模型,并分析通孔直径、位置等关键参数对滤波器性能的影响。针对基于中心位置的SIW带通滤波器带宽较窄的问题,提出偏置金属通孔SIW带通滤波器的设计方法,从而增大滤波器的带宽。并通过对改进后的基片集成波导带通滤波器的仿真,验证了设计的正确性和方法的有效性。

| Abstract: | In this paper,a Ku band bandpass filter used in the mobile communication is presented by using the substrate integrated waveguide (SIW) technology.The equivalent circuit of the perceptual metal patch in the SIW is described.The transition characteristics of filter are simulated and the parameters of structure analyzed.An improvement of the bandpass filter bandwidth is achieved by comparing two design methods.The result of the simulation shows that this approach is feasible and effective. |
