【摘要】 本文介绍了一种新型混合左右手传输线具有两个通带。该左手材料(Left-handedmetamaterials,LHMs)在通带内呈现介电常数和磁导率同时为负。本文介绍了混合左右手材料传输线的传输特性和分析方法。混合左右手材料的两个通带分别出现在2.8GHz和5.8GHz处。通过仿真得到了色散曲线,折射率,等效介电常数,等效磁导率,从理论上验证了左手特性的存在。具有双通带的混合左右手传输线将会在未来大量的双频带器件的应用中发挥重要的角色。更多还原

【Abstract】 A novel composite right/left-handed transmission line(CRLH-TL) meta-material is proposed with two pass bands,in which the permittivity and permiability are both nagitive.The topology and method of operation of the line are discussed.The two pass band of the CRLH-TL are existed at,2.8GHz and 5.8GHz respectively.The measured results of dispersion curves,index of refraetion,peimittivity and permiability are in agreement with those of simulation and theory.A CRLH-TL with two main pass bands would play an important part in a number of quad-band applications.更多还原
