| 摘 要： | 从理论上解释了左手材料用于天线设计时实现天线高指向性、高效率、小型化以及大扫描范围的原因,重点介绍了基于金属谐振结构和复合左/右手传输线(CRLH TL)结构的左手材料用于天线设计时的研究进展,指出金属谐振结构在提高天线方向性、增大天线增益、减小天线体积等方面具有很大优势,CRLH TL结构在提高天线带宽、增加天线频带、增大漏波天线扫描范围等方面具有潜在的应用价值。

| Abstract: | The reasons of high-directivity,high-efficiency,miniaturization and large scanning range of antennas designed by left-handed materials are explained.The research progress on antennas design by left-handed materials based on both resonant metal structures and composite right/left-handed transmission line(CRLH TL) structures are reviewed.It is shown that the resonant metal structures can be used to improve the antenna directivity,gain and reduce the antenna size,while the CRLH TL structures have potential app... |
