基于左手介质的贴片天线技术研究

介绍和分析了左手介质的构造原理和方法，通过对加载左手介质材料的贴片天线的研究，来说明左手介质天线的一些优异特性。仿真和实测结果表明，通过加载左手介质材料，普通贴片天线会产生新的特性，如工作频率的降低、天线增益的提高、方向性的增强等。而且，天线的物理尺寸能得到很大的减小，这就为高增益、高带宽的小型化贴片天线设计提供了新的方法和思路。

Research on Patch Antenna Loaded by Left-hand Material

This paper describes and analyzes the construction principles and methods of Left-Hand Material.By the studyof patch antennas which are loaded with Left-Hand Material,we illustrate the excellent characteristics of them.Simulation andexperimental results show that ordinary patch antenna will have new features by loading Left-Hand Material,such as loweroperating frequency,increases of antenna gain,enhance of the direction and so on.Moreover,the physical size of them can begreatly reduced,which can provide new methods and ideas of designing small antenna with high gain and wide bandwith.
