摘要

本文介绍了衬底集成波导(SIW)带通滤波器的设计过程。中心频率为18GHz，带宽约为1GHz。在计算出K逆变器的$\frac{K}{Z_{0}}$后，我们可以用并联电感和传输线代替K逆变器。最后，利用曲线拟合分析找出了虹膜窗(W)与电感器之间的关系。通过这些程序设计了18GHz的SIW带通滤波器。

Design SIW iris bandpass filter at 18GHz

This paper shows rough procedure to design Substrate Integrated waveguide (SIW) bandpass filter. The center frequency is at 18GHz, and the bandwidth is about 1GHz. After calculating $\frac{K}{Z_{0}}$ of K-inverter, we can substitute parallel inductor and transmission line for K-inverter. Finally, using curve fitting analysis to find the relation between iris window(W) and the inductor. The SIW bandpass filter at 18GHz have been design through these procedures.
