摘要

本研究利用特征模态分析（CMA）研究全向天线的设计，并探讨两种不同的馈电方法。第一种方法在所有端口上采用等幅和同相激励，而第二种方法在相邻端口之间使用180°相位差的等幅激励。两种设计分别实现了2.45-2.58 GHz和2.42-2.45 GHz的工作带宽，在2.45 GHz时的峰值增益分别为4.1 dBi和4.4 dBi。所提出的天线具有高增益和低调的特点，使其非常适合无线能量收集的应用。

Designed Omnidirectional Antenna of Quarter-Mode Substrate-Integrated Waveguide Element with Characteristic Mode Analysis.

This study investigates the design of omnidirectional antennas, using a characteristic mode analysis (CMA), and explores two distinct feeding methods. The first method employs equal-amplitude and in-phase excitation across all ports, whereas the second method utilizes equal-amplitude excitation with a 180° phase difference between adjacent ports. Both designs achieve operating bandwidths of 2.45-2.58 GHz and 2.42-2.45 GHz, respectively, with peak gains of 4.1 dBi and 4.4 dBi at 2.45 GHz. The proposed antennas exhibited high gain and low-profile characteristics, making them well-suited for applications in wireless energy harvesting.
