摘要 一种均匀面片尺寸的图钉型电磁带隙结构只能实现一个表面波带隙,而将不同参数的图钉型电磁带隙结构级联可以实现多个或宽带的表面波带隙。利用不同金属面片尺寸的图钉型电磁带隙结构级联的方法实现双带的表面波带隙。设计两种均匀的电磁带隙结构,使其带隙范围分别覆盖天线的两个工作频带,然后将这两种结构级联起来,加载于两个缝隙天线单元之间。仿真分析和实验结果表明,级联型的电磁带隙结构可以有效抑制表面波,在两个频率带内同时减小互耦。 A uniform mushroom-like electromagnetic band-gap（EBG） structure can realize only one surface-wave suppression bandgap.Hence,two kinds of units with different parameters mushroom-like EBG structures are cascaded to realize the dual-band or broadband surface-wave suppression bandgap.This paper presents a dual-band EBG structure using cascaded mushroom-like structures with different patch sizes.Two kinds of uniform EBG structures are used to produce two suppression surface-wave bandgaps covering the two operating frequency respectively.The cascaded structure is integrated between slotted microstrip antennas.Simulation and experimental results show that the cascaded structure can suppress the surface-wave effectively and decrease the mutual coupling of the two operating frequencies at the same time.
