本文提出了一种具有多个陷波带的超宽带带通滤波器。超宽带的带通特性是通过一个改进的分布式高通滤波器（HPF）和抑制高次谐波的HPF通过实现缺陷阶梯阻抗谐振器。通过在主微带线上嵌入两个开放短截线，获得了5.75和8.05 GHz的双频段陷波。通过全波电磁仿真、等效电路模型和实测得到的带内、带外特性吻合较好。
In this letter, an ultra-wideband (UWB) bandpasss filter with multiple notch bands is presented. The UWB bandpass characteristic is achieved using a modified distributed highpass filter (HPF) and suppressing higher order harmonics of the HPF by realizing defected stepped impedance resonator. The dual band notches at 5.75 and 8.05 GHz are obtained by embedding two open stubs on the main microstrip line. The in band and out of band performance obtained from fullwave electromagnetic simulation, equivalent circuit model and measurement are in good agreement.
