【摘要】 本文提出了一种基于共模/差模理论的方向图可重构天线。该天线由一个正交辐射贴片和一个可重构馈电网络构成。利用共模/差模理论,通过切换并组合馈电端口实现三种模式方向图之间的重构（共计九种状态）。仿真结果表明,不同状态下,该天线在4.24 GHz～4.52 GHz频带范围内|S₁₁|小于-10 dB,增益大于5.06 dBi,具有结构简单、可重构状态多等优点,可应用于sub-6G通信等场景。更多还原

【Abstract】 A pattern-reconfigurable antenna based on the theory of common and differential modes（CM/DM） is proposed in this paper.The antenna is composed of an orthogonal radiation patch and a renconfigurable feeding network.Based on the theory of CM/DM,three-mode reconfigurable patterns（nine states in total） can be realized by switching and combining the feedeing ports.For all the nine states,the simulated results demonstrate that within 4.24 GHz～4.52 GHz,|S₁₁| are less than-10 dB and the gains are more than 6.78 dBi.With excellent performances of simple structure and multi reconfigurable patterns,the antenna can be applied to the sub-6 G communication.更多还原
