摘要:

使用HFSS仿真软件设计了基于基片集成玻导（substrate integrated waveguide，SIW)的带通滤波器。在SIW腔体中加入金属圆柱扰动，形成带通滤波器，并通过调节扰动金属柱的半径来调整带通滤波器的频带宽度和中心频率，最后在Rogers 5880介质基板制作实物。测试结果表明：中心频率为24 GHz，通带内插入损耗2.4 dB、回波小于-15 dB的带宽为300 MHz。仿真结果和实验测试结果基本相符。此带通滤波器能够应用在汽车雷达系统中。

Abstract:

The substrate integrated waveguide (SIW) has numerous benefits，such as low insertion loss，high capacity，high quality factor and easily mass production.Due to SIW technology,the SIW bandpass filter is designed and simulated by HFSS simulation software in this paper.The characteristics of bandpass filter are formed by adding perturbations of metallic post in the SIW cavity.The bandwidth and center frequency of bandpass filter are adjusted by altering the radius of perturbations of metal cylinder.Finally，the filter is made on the substrate of Rogers 5880，the results are indicated：the center frequency is 24 GHz，insertion loss is 2.4 dB，the bandwidth is achieved 300 MHz that return loss is less than 15 dB.Simulation and examination results on the SIW bandpass filter show good agreement.This filter can be applied in circuits of automotive radar.
