该文运用HFSS和S参数模型,分别从时域和频域的角度通过仿真实验研究和分析了电磁带隙(EBG)结构对信号传输特性的影响,研究表明EBG结构的周期性高阻平面导致了传输信号的反射与滤波,严重影响了信号传输质量。平面周期越小,影响越大。最后通过实验仿真和理论分析给出了EBG结构的应用规则。
The influence of Electromagnetic Band-Gap (EBG) structure on signal transmission is investigated in this paper. The signal integrity in time domain and frequency domain is analyzed by HFSS and S parameter model. The simulation results show that the signal reflection and filter are induced by periodic structure, signal quality is affected seriously .The smaller period is, the worse signal quality is. Finally, the design rules for high-speed circuit in EBG structure are derived from the results obtained.
