【摘要】 本文提出了一种基于人工表面等离激元的高模态平面螺旋轨道角动量模群天线。文章基于部分弧发射方案,利用人工表面等离激元作为天线模型,设计了在主瓣内具有稳定相位线性度的平面螺旋轨道角动量模群。该模群具有高等效OAM模态以及高增益,同时具有可观的带宽,在MIMO通信系统及雷达转速测量系统中均具有应用前景。更多还原

【Abstract】 In this paper,a high-mode plane spiral orbit angular momentum mode group(PSOAM MG) antenna based on spoof surface plasmon polaritons(SSPP) is proposed.This antenna is designed based on the partial arc transmitting PAT) scheme.Using the SSPP as the antenna model,a PSOAM MG with stable phase linearity in the main lobe isachieved.The mode group has a high equivalent OAM order,high gain and considerable bandwidth,which will have a promising application prospect in MIMO communication system and radar rotational speed measurement system.更多还原
