Abstract

A 3D printed antenna embedded in a 3D printed ring for 5G millimeter wave applications is proposed. Two additive manufacturing (AM) methods have been combined in a single machine to develop the structure. Fused filament fabrication (FFF) was used to make the substrate of the antenna and supporting ring while direct write with conductive paste was used to create the antenna radiator. Polylactic acid (PLA) plastic was used in the development of the dielectric layers while the metallic patch of the radiator was created using silver paste. Reflection coefficient and radiation pattern of the ring antenna were tested in free space and worn on a hand phantom. The hand phantom was developed using pork sausages placed inside a thin glove. The design and simulations were carried out in CST Microwave StudioTM. Measured results show consistency with the simulated results. The antenna operates satisfactorily at the proposed 5G millimeter wave communication band. This work aims to demonstrate a concept of millimeter wave 3D printed ring antennas and the development and use of sausage-based hand phantoms for antenna measurements.

3D打印毫米波天线集成到5G应用环中

提出了一种用于5G毫米波应用的3D打印天线嵌入3D打印环。两种增材制造(AM)方法结合在一台机器上来开发结构。采用熔丝法制作天线衬底和支撑环，采用导电浆料直接写入法制作天线散热器。电介质层采用聚乳酸(PLA)塑料，散热器的金属贴片采用银膏状材料。在自由空间测试了环形天线的反射系数和辐射方向图，并戴在手模上。这只手的“幻影”是用夹在薄手套里的猪肉香肠制成的。在CST Microwave StudioTM中进行了设计和仿真。实测结果与仿真结果基本一致。该天线在拟议的5G毫米波通信频段上运行良好。这项工作旨在展示毫米波3D打印环形天线的概念，以及用于天线测量的基于香肠的手模型的开发和使用。
