摘要

辐射轨道角动量（OAM）模式的天线通常很大，结构复杂。本文结合特征模态分析，采用地平面作为OAM波辐射器。为了使用单馈结构激发具有相位正交的接地平面的简并模式，在矩形接地平面周围引入两个具有接地端的弯曲金属带，并将其中一个弯曲金属带的角设置为馈电点。对于地辐射器，通过合成简并模式，在高频端产生一阶OAM模式。在弯曲侧带的情况下，形成在低频模式下操作的倒F天线。这种紧凑型天线具有双频带特性，便于简单馈电，适用于移动终端应用。

Dual-Band Antenna with OAM Mode Radiated by Ground Plane

Antennas that radiate orbital angular momentum (OAM) modes are usually large and have complex structures. In this paper, in combination with characteristic mode analysis, the ground plane is used as the OAM wave radiator. To excite degenerate modes of the ground plane with phase quadrature by using a single-fed structure, two bent metal strips with grounded ends are introduced around the rectangular ground plane, and a corner of one of the bent strips is set as the feeding point. For ground radiators, a first-order OAM mode is generated at the high-frequency end by synthesizing the degenerate modes. In case of the bent side strip, an inverted-F antenna that operates in the low-frequency mode is formed. This compact antenna has dual-band characteristics and facilitates simple feeding, which makes it suitable for mobile terminal applications.
