摘要:
提出了一种将哑铃型DGS中的长方形缝隙变为蛇形缝隙的蛇型DGS,建立了等效电路模型并进行参数推导.基于控制变量法分析参数变化对蛇型 DGS结构频率特性及等效电路参数的影响.将该结构应用于低通滤波器的设计,分别在HFSS和MATLAB环境下对设计的滤波器及其等效电路模型进行仿真,两种方法的仿真结果具有很好的一致性.结果表明,该结构可在不增加缺陷面积的情况下得到更低的衰减频率和更多的谐振频率点.
Abstract:
A snake DGS defect structure which uses snake-like gap instead of rectangular gap into the dumb-bell DGS is introduced. An equivalent circuit is built,meanwhile,the relevant circuit parameters are derived.Control variate method is used to analyze the influence of parameters variation to frequency characteristics andcircuit characteristics of the snake DGS defect structure. Furthermore,this kind of structure is put into the de-sign of low-pass filter,simulation of the designed filter and its equivalent circuit model is done separately byMATLAB and HFSS. The results of these two methods are coincident. So it can be drawn that the structurehas lower attenuation frequency and more resonant frequency in the case of maintaining the area of the defects.
