中文摘要：

提出了一种小型化电负波导超材料单元，深入研究了其电磁特性，并通过MATLAB编程提取了它的本征参数，证明了其电负特性。根据其在电负频段谐振产生阻带这一特性，设计了一款工作在WIMAX（3．5GHz）的2单元微带天线阵。与参考天线阵相比，加载超材料单元的天线阵互耦下降了8．3dB，天线间距缩小为λ／14（λ为天线在自由空间工作波长），并且天线阵的远场辐射性能还有所提高。因此，该新型电负波导超材料单元在设计高性能天线阵方面具有广阔应用前景。

英文摘要：

A novel compact waveguided electric metamaterials is proposed, and its electromagnetic characteristics are investigated. The constitutive parameters of the proposed structure have been extracted by standard retrieval procedure using MATLAB and the single-negative electric characteristic is proved. Two microstrip antenna arrays working at 3.5GHz （Wimax） are designed using the proposed CSSRR-loaded electric WG-MTMs, a mutual cou- pling reduction of 7.6dB compared to the reference antenna has been realized for the proposed WG-MTM antennas. The resultant antenna array exhibit a small separation （L/8 at the operating wavelength）. Moreover, the antennas＇ far-field radiation performances have been improved. Thus, tion ability, but also can optimize the other performances of new types of antenna with super performances. this novel WG-MTM not only has good coupling reducthe antennas. The proposed strategy opens an avenue to new types antenna with super performances.
