摘　　要：滤波器是微波毫米波电路与系统中的一个重要部件.基片集成波导技术使得包括平面电路、接头和矩形波导在内的完整电路可以平面的形式集成在标准印刷电路板上.本文将偏置介质销钉带通滤波器的设计方法引入基片集成波导中,实现了一个中心频率为28GHz,相对带宽为3.57%的基片集成波导带通滤波器,Ansoft HFSS的数值计算结果显示该途径是成功的.Filters is a kind of important components in microwave and millimeter wave circuits and systems. The substrate integrated waveguide technique makes it possible that a complete circuit including planar circuitry, transitions, and rectangular waveguides is fabricated in planar form using a standard printed circuit board. In this paper, a filter design method derived from a synthesis technique using offset dielectric posts is presented. To validate the approach presented, the filter is designed at the center frequency of 28GHz with 3.57% fractional bandpass width. The result is validated by numerical simulation on the basis of Ansoft HFSS.
