摘要

本文介绍了特征模态的特性，并利用特征模态分析(CMA)提出了一种优势模态和高阶模态的选择性激励方法。平台的CMA分析结果表明，低阶模具有与偶极子天线相似的辐射方向图。在平台表面边缘放置4个倒f天线。这四个反f天线通过选择合适的馈电位置激发平台的主导模式和更高模式。

Selective Excitation of Platform Eigenmodes Using Characteristic Mode Theory

This paper presents characteristics of eigenmodes, and a selective excitation method of a dominant and higher modes using Characteristic Mode Analysis (CMA). The results of CMA of the platform shows that lower order modes have radiation patterns like dipole antenna. Four inverted-F antennas are placed at the edge on platform surface. These four inverted-F antennas excite dominant and higher modes of the platform by selecting appropriate feed position.
