摘要
针对业界广泛讨论的20 H规则边缘辐射进行仿真分析.采取基于腔模理论,对四层PCB板场的理论分析,建立了以微带天线为结构的模型,并进行了模型理论分析与仿真对比验证.仿真结果表明:20 H规则在四层PCB板中的应用是不能达到减少边缘辐射效果的.
In the paper, the simulated analysis on 20 H rule which is discussed broadly in PCB design field has been done. Based on Resonant cavity theory, the microstrip antenna model is extracted from a 4 layer PCB. Series of simulation figures and theoretical analysis are carried out. The simulated result shows that the 20 H rule is invalid in 4 layer PCB application.
