本文介绍了一种采用激光直接结构（LDS）技术制作的紧凑的+/- 45度极化基站天线阵列。拟议的天线阵列在第五代（5G） NR频段41 （2496-2690 MHz）中运行。该阵列的简单天线单元由改进的贴片辐射体组成，该贴片辐射体由注射成型的y形探头馈送，适合于高效的批量生产。为了满足实际基站应用的规范要求，研究了天线单元（AU）。制作了AU样机并对其进行了测量，结果表明该样机在工作频带内能够满足设计要求。这些特点也表明，这种基于lds的天线阵列将是5G基站应用的一个有前途的解决方案。
In this letter, a compact +/- 45 degrees polarized base station antenna array fabricated using laser direct structuring (LDS) technique is presented. The proposed antenna array operates in fifth-generation (5G) NR band 41 (2496-2690 MHz). The simple antenna elements of the array consist of a modified patch radiator fed by Y-shaped probes realized by injection molding, which are amenable to efficient mass production. An antenna unit (AU) is investigated to meet the specification requirements in practical base-station applications. A prototype of the AU was manufactured and measured, and the results showed that it is able to fulfill the design requirements within the operating band. These features also show that this LDS-based antenna array would be a promising solution for 5G base station applications.
