This article presents a fully 3D-printed dielectric planar lens operating in the entire Ka-band manufactured using additive manufacturing and a relatively low-cost 3D-printer. The lens consists of ten concentric rings implemented using low-loss ABS filaments with high permittivity values. By varying the infill percentages of them the required refractive indexes of each section are achieved. An additional 3D-printed matching layer, using the same manufacturing and design method was included in the lens, to reduce reflections. Simulation and measurement results show a very good agreement, which confirms the possibility of manufacturing a cost-effective broadband and planar lens solution operating in millimeter wave bands, where Low Earth Orbit Satellites (LEO) networks, future mobile communication systems (5G, 6G) and radar systems operate.
本文介绍了一种完全通过3D打印制造的介质平面透镜，其工作在整个Ka波段，采用增材制造技术和相对低成本的3D打印机。该透镜由十个同心环组成，使用具有高介电常数的低损耗ABS细丝制成。通过改变它们的填充百分比，可实现每个部分所需的折射率。透镜中还包括一个采用相同制造和设计方法的3D打印匹配层，以减少反射。仿真和测量结果显示出非常好的一致性，这证实了制造一种经济高效的宽带平面透镜解决方案的可能性，该解决方案可在毫米波频段工作，低地球轨道卫星（LEO）网络、未来移动通信系统（5G、6G）和雷达系统都运行在该频段。
