【摘要】 本文设计了一个基于3D打印技术的毫米波全介质多波束透镜天线,透镜的孔径相位分布通过路径补偿相位和周期相位的叠加生成。首先设计了一款全介质结构的单元,该单元内部集成了周期性抗反射(AR)结构,以最小化空气与介质界面处的阻抗失配,通过调节介质单元的高度可以实现0-360°的移相。基于这种全介质单元,采用喇叭天线作为馈源,设计并仿真了一款14×14的透镜天线。仿真结果表明,该多波束透镜天线能够在28 GHz-38GHz频段内,实现-27°、0°和27°三个独立方向的波束生成。更多还原

【Abstract】 This paper presents a millimeter-wave all-dielectric multi-beam lens antenna fabricated using 3D printing technology,where the aperture phase distribution is achieved by superimposing path compensation and periodic phases.A unit cell with an integrated periodic anti-reflection(AR)structure is designed to minimize impedance mismatch at the air-dielectric interface.By adjusting the height of the dielectric unit,a phase shift range of 0–360° is achieved.Utilizing this all-dielectric unit,a 14×14 lens antenna is designed and simulated with a horn antenna as the feed.Simulation results demonstrate that the proposed tri-beam lens antenna can generate three independent beams at-27°,0°,and 27° within the 28 GHz to 38 GHz frequency band.更多还原
