In this article, a novel lens antenna with wide beamwidth using three-dimensional printing is proposed. The proposed antenna is comprised of a concave lens by using three-dimensional printing, a lantern shaped patch with a parasitic ring, and eight loaded monopoles around the center. The antenna operating frequency is 5.8 GHz, and the prototype is implemented. The measured half power beamwidth are 142° and 130° at the xoz and the yoz planes, respectively. Besides, the antenna is low cost, easy to fabricated, and very low cross polarization. Measured results agree well with the simulation results.

一种采用三维打印的宽波束新型透镜天线

在本文中，提出了一种使用 3D 打印的具有宽波束宽度的新型透镜天线。所提出的天线由使用 3D 打印的凹透镜、带寄生环的灯笼形贴片和围绕中心的八个加载单极子组成。天线工作频率为5.8 GHz，并实现了原型。在 xoz 和 yoz 平面测得的半功率波束宽度分别为 142° 和 130°。此外，该天线成本低，易于制造，交叉极化极低。实测结果与仿真结果吻合良好。
