摘要

提出了一种基于等效电路的电源平面电磁带隙结构建模和分析的新方法。平面EBG结构分为单元和连接部分,将积分方程多端口网络与微带传输线相结合,开发了等效电路。通过电路仿真得到了EBG结构的阻带隙。通过测量和全波仿真验证了所提出的方法,所提出的EBG结构显示出0.7-3 GHz的阻带隙,插入损耗小于-50 dB。

Modelling of planar EBG structure by using equivalent circuit method
A novel method based on equivalent circuit is presented to model and analyze the EBG(Electromagnetic Band Gap) structure of power planes. The planar EBG structure is divided into cells and connecting parts, the equivalent circuit is developed by combining the integral equation multi-port networks and the micro-strip transmission lines. The stop bandgap of the EBG structure is obtained by the circuit simulation. The proposed method is validated by both measurement and full-wave simulation, where the proposed EBG structure shows the stop bandgap at 0.7-3 GHz with less than -50 dB insertion loss.
