【摘要】 本文提出了一种基于人工等离激元结构(SSPP)的宽带四端口全空域二维扫描相模天线。通过将SSPP多枝节辐射体折叠,通过多端口馈电和相模激励技术实现全空域波束灵活调控。基于四端口馈电网络与特定辐射结构,天线可在上半球空间内实现连续的二维波束扫描,覆盖全空域。天线在2.01～3.21 GHz内实现VSWR<2(相对带宽46.3%),且在宽频带内保持良好的端口隔离度,在上半球空间内实现连续的二维波束扫描,最大扫描俯仰角90°,方位角全覆盖。更多还原

【Abstract】 This paper presents a broadband four-port full-space two-dimensional scanning phase-mode antenna based on spoof surface plasmon polariton(SSPP) structures.By folding the multi-branch SSPP radiators and employing multi-port feeding with phase-mode excitation techniques,flexible full-space beam steering is achieved.Utilizing a four-port feeding network and a specially designed radiation structure,the antenna enables continuous 2 D beam scanning across the entire upper hemisphere.The prototype operates from 2.01 to 3.21 GHz(46.3% fractional bandwidth) with VSWR<2,while maintaining good port isolation across the bandwidth.Continuous beam scanning is demonstrated with a maximum elevation angle of 90° and full azimuthal coverage.更多还原
