摘要

本研究旨在利用特征模式分析（CMA）设计一种圆极化紧凑型天线。所提出的天线由带有开槽环形贴片的基板和部分接地组成。通过对CMA不同工作模式的分析，确定了天线的激励位置及其最佳尺寸。然后，设计了一个优化的天线，并制作了天线原型进行验证。实验结果表明，反射系数的-10dB阻抗带宽为6.85GHz，3dB轴比带宽为0.7GHz，峰值增益为3.2dBi。这些特性与仿真结果一致，使圆极化紧凑型天线适用于C波段和低于6GHz的5G无线应用。

Compact Circularly Polarized Monopole Antenna Using Characteristic Mode Analysis

This study aims to design a circularly polarized compact antenna using characteristic mode analysis (CMA). The proposed antenna consists of a substrate with a slotted annular ring-shaped patch and partial ground. The excitation position of the antenna and its optimal dimensions are determined through the analysis of different operation modes with CMA. After that, an optimized antenna is designed, and an antenna prototype is fabricated for validation. The experimental results show that the reflection coefficient achieves a -10dB impedance bandwidth of 6.85 GHz, a 3dB-axial ratio bandwidth of 0.7 GHz, and a peak gain of 3.2 dBi. These characteristics agree with simulations and make the circularly polarized compact antenna suit for C-band and sub-6 GHz 5G wireless applications.
