摘要 轨道角动量作为一种新的、安全和高效利用频谱的传输复用方式引起了科学界的关注。基于均匀圆阵列,设计了一种工作在X波段的宽带多模轨道角动量天线。该天线由旋转排列的三角形均匀圆阵列组成,其特点是正负模式数的产生除了与馈电方式有关外,还与均匀圆阵中阵元的旋转方式相关。仿真结果表明,在X频段该天线-10 d B带宽范围为9. 33~10. 37 GHz,带宽达到1. 04 GHz,总的效率为52%;在相同阵元数量的情况下,该天线产生的模式数多于矩形贴片天线。该天线具有馈电网络简单、带宽宽和模式数大等优点。 As a novel,safe and high efficient spectrum utilization technology,orbital angular momentum(OAM)has attracted a great deal of attention in scientific community.In this paper,a broadband and multimode OAM antenna which works in X-band is designed based on uniform circular array(UCA).The antenna is composed of rotatingly arranged triangular element uniform antenna array.Its characteristic is that the number of positive and negative modes is related to the feed mode and the rotation mode of the array elements in the uniform circular array.Simulation experiments show that the antenna works at X band(9.33-10.37 GHz)and bandwidth is 1.04 GHz,relative bandwidth is 52%,and the modes of this antenna is more than the rectangular patch antenna with same number of elements.The antenna has the advantages of simple feeding network,wide bandwidth and easy control of the number of modes.
