摘　　要：本文通过对电磁带隙(EBG)结构等效电路的分析,研究了展宽其带隙带宽的方法,提出了一种新型的实现方法——组合单元法.以金属贴片表面螺旋电感的EBG结构为例,验证了该方法的有效性和正确性.为解决EBG结构存在的带隙带宽较窄的问题提供了一种新的思路.The equivalent circuit model for electromagnetic band-gap structure（EBG）is analyzed in this paper, and also the methods of broadening the bandwidth of band-gap are studied. A novel method, which is called ＂United Cells Method＂, to broaden the bandwidth of band-gap of EBG structure is proposed, The correction and validity are confirmed, by the results of software-simulations and experiments, using mushroom-like EBG structure with spiracle inductance on patches. This method gives a novel mind to broaden the bandwidth of EBG structures.
