摘要
介绍了一种将阶梯阻抗耦合谐振器和开口谐振环缺陷接地结构相结合的新的超宽带带通滤波器。利用3D场仿真软件,分析了电路的不同支节尺寸对滤波器宽带特性和频率特性的影响,最后给出了一款超宽带滤波器的仿真和实验结果。
A new ultra-wideband band-pass filter combining the step-impedance coupling resonator and the split-ring resonator defected ground structure（SRR DGS） is introduced.The effects of the different dimensions of the circuit stubs on the characteristics of the wideband and frequency of the filter are analyzed through the 3D EM field simulation software.Finally,the simulation and test results of the ultra-wideband filter are given.
