摘要
利用三维场分析法分析了DGS微带线的频率特性,利用电路分析法讨论了DGS微带线的等效LC电路及其参数提取。然后讨论了哑铃的形状、大小、间隙以及介质介电常数对其频率特性的影响。最后给出采用DGS微带线设计的低通滤波器的仿真结果和实验测试结果。
The frequency characteristics of the microstrip line with DGS are simulated by means of 3-D field analysis, and its equivalent circuit and equivalent parameters extraction are analyzed. Then the influences of dumbbell shape and the material permittivity on frequency characteristics are discussed. Experiment results of low-pass filter using microstrip line with DGS and simulation results are given at last.
