摘　　要：利用复合左/右手传输线理论(CRLHTL)和零阶谐振器理论(ZOR)对多孔型的电磁带隙结构(electromagnetic band-gap,EBG)的带隙特性作了分析研究.同时,利用电磁仿真软件HFSS对多孔型EBG结构单元和加载多孔型EBG结构的阶梯型微带天线进行了仿真分析,结果表明:通过选择合适的多孔EBG结构表面参数,可实现电磁特性的可控性.将多孔型EBG结构加载在阶梯型微带天线设计中,不仅能利用其带隙结构的特性改善天线的辐射特性,制约表面波的传播,提高天线的带宽和增益,而且能使天线结构更加紧凑,有利于实现集成化和小型化.这为含有多层多孔型EBG结构阶梯型微带天线设计提供了理论基础,具有一定的工程实际参考价值.The band gap characteristics of porous EBG（Electromagnetic band-gap）structure were analyzed by using the composite left/right handed transmission line（CRLHTL）theory and the zero order resonator（ZOR）theory.At the same time,the electromagnetic simulation software HFSS was used to simulate the porous EBG structure unit and the ladder shaped microstrip antenna loaded with porous EBG structure.The results show that the controllability of the electromagnetic properties can be achieved by selecting the appropriate surface parameters of the porous EBG structure considering the band gap structure characteristics,the porous EBG structure in the design of ladder type antenna loaded microstrip antenna can improve the radiation of the antenna,restrict the propagation of the surface wave propagation constraints,and improve the band width and gain of antenna.The structure of the antenna is more compact,which is innfavaur of integration and miniaturization.The work provides a theoretical basis of design of multilayer porous type the EBG structure of the ladder type microstrip antenna and practical reference value for engineering.
