摘要

提出了一种电小方向图可重构天线。它允许通过在两个端口之间施加相移来调整辐射模式。结构为直径为λ/5的圆柱体。仿真结果表明，该系统在2.44 GHz频段运行良好，并且通过施加三种不同的相移可以得到三种不同的辐射方向图。基于球面模态理论，阐述了天线的工作原理和局限性。

Electrically small antenna with switchless pattern reconfiguration

An electrically small pattern reconfigurable antenna is proposed. It allows adjustment of the radiation pattern by applying a phase shift between its two ports. The structure is a cylinder with λ/5 diameter. Simulated results show good operation at 2.44 GHz and three different radiation patterns are demonstrated by applying three different phase shifts. The antenna's principles of operation and limitations are explained based on the theory of spherical modes.
