中文摘要：

基于超介质的相位超前理论,设计了一种新型的串联线性偶极子阵列。该阵列利用负折射指数相移线代替传统一个导波波长（λg）的弯折线进行馈电。其中,NRI相移线采用CPS技术,并通过在主传输线上周期性地加载串联电容和并联电感来实现。研究结果表明：串联馈电线性偶极子天线具有带宽宽、体积小、波束倾斜小、制作简单、易于集成等优点。

英文摘要：

A novel series-fed linear antenna arrays based on negative refractive index theory is presented.The negative refractive index（NRI） media implemented by periodically loading host transmission-lines（TL） with lumped-element series capacitors and shunt inductors.The proposed series-fed linear antenna arrays employs metamaterials phase-shifting lines,instead of the conventional a one guided wavelength（λg） long meandered TL to feed.Both the metamaterials and TL arrays were designed in co-planar strip（CPS） technology.The proposed arrays shows a relative broad bandwidth,array patterns experience less beam squint with frequency when compared to their conventional series-fed counterparts.Moreover,it is compacted and easily to implement and integration.
