摘要

特征模式分析（CMA）可以用于天线设计以解决辐射问题。这篇综述的重点是圆极化（CP）天线的现有开发方法，以及使用CMA改进其轴比带宽（ARBW）。为了讨论与CP辐射相关的物理见解，本研究系统地研究了先前研究中使用的不同天线设计结构。研究了各种天线设计的模态参数，如特征值、模态显著性（MS）、特征角（CA）、表面电流、远场辐射行为对CP辐射和ARBW的影响。此外，还讨论了从天线性能参数（如工作频带、ARBW和增益）方面对各种天线设计方法的比较分析。结果表明，与传统的全波仿真方法相比，CMA为天线设计中馈电位置的选择提供了更有价值的信息。

Circularly Polarized Antennas Using Characteristic Mode Analysis: A Review

Characteristic mode analysis (CMA) can be used in antenna designs to solve radiation problems. This review focuses on the existing development methodologies for circularly polarized (CP) antennas and their axial ratio bandwidth (ARBW) improvement using CMA. To discuss the physical insights related to CP radiation, this study systematically examines different antenna design structures used in previous research. It investigates the impact of modal parameters such as the eigenvalue, modal significance (MS), characteristic angle (CA), surface current, far-field radiation behavior on CP radiation, and ARBW for various antenna designs. In addition, it discusses the comparative analysis of various antenna design approaches in terms of antenna performance parameters such as the operating frequency band, ARBW, and gain. The results show that CMA provides more valuable information for the selection of feed position in antenna designs than the conventional full-wave simulation approach.
