摘要
提出一种采用3D打印技术设计制造的径向开孔分层龙伯透镜天线,该天线以低损耗的石蜡强化聚苯乙烯为基材,透镜直径为700mm,结构形式为7层半球龙伯透镜.天线工作在Ku/Ka频段,可同时对准两个目标.研究表明:采用3D打印技术制造的低损耗介质径向开孔分层龙伯透镜天线实现了较高性能,有效解决了传统加工方式加工困难、一致性差的问题,可以容易地通过采用更小介电损耗的材料实现更优良的天线性能.
A 700mm diameter 7-layered hemisphere Luneburg lens antenna with radically drilled holes structure using paraffin reinforced polystyrene based on 3D printing is proposed. Operating at Ku/Ka band, the antenna can simultaneously aim at two targets. With high performance, the lens antenna effec- tively solves the processing difficulty and anisotropy of traditional processing method, and easily realizes superior performance through using lower dielectric loss materials.
