特征模在超宽带和多输入多输出天线设计中的应用
内容简介:特征模理论通过分析天线的特征值,把表面电流分解成相应的特征电流,并可进一步得到天线的特征方向图。它可以从物理本质上研究天线的辐射机理,从而有效指导天线设计。在简要介绍了特征模理论之后,详细说明了它在超宽带天线和多输入多输出天线的分析设计方面的应用,并指出了它的应用前景。
Abstract:By analyzing the eigenvalues of antenna,the eigenmode theory decomposes the surface current of antenna into a series of orthotropic eigencurrents,and further provides the eigenpattern.Thus,this theory can provide physical insights into the radiation mechanism of antennas and guidance to the antenna design.In this paper,a review of eigenmode theory is described.Then,a detail introduction to the application of eigenmode theory in the analysis and design of ultra-wideband(UWB) antennas and multi-input multi-output(MIMO) antennas is provided.The future of this method in the analysis and design of antennas is indicated.
