论文摘要
本文介绍了低成本的设计和原型多重输入多重输出（MIMO）天线，用于5G和毫米波（MM-WAVE）。提出的模仿是使用3D打印制造的，并且能够在多个方向上传递梁，这些方向可在不使用相位变速器的情况下提供连续和实时的覆盖范围。这使拟议中的MIMO具有在5G和MM波应用中成为有吸引力的低成本技术的优势。所提出的MIMO天线在28 GHz 5G频带上运行，具有宽的带宽性能超过4 GHz，并且在高程平面中具有高达30°的光束开关能力。通过引入一个3D打印的墙壁，在整个带宽上，单个元素天线的主梁的方向在整个带宽上转向，在3D打印的辐射天线的侧面具有不同的高度。与所有其他可用的光束转向技术不同；所提出的壁不仅能够改变天线的光束的方向，而且还能够同时在整个带宽中同时提高所提出的天线和MIMO的总体方向性和增益。
This paper presents designs and prototypes of low cost multiple input multiple output (MIMO) antennas for 5G and millimetre-wave (mm-wave) applications. The proposed MIMOs are fabricated using 3D printing and are able deliver beams in multiple directions that provide continuous and real time coverage in the elevation of up to 30° without using phase shifters. This equips the proposed MIMO with a superior advantage of being an attractive low cost technology for 5G and mm-wave applications. The proposed MIMO antennas operate at the 28 GHz 5G band, with wide bandwidth performance exceeds 4 GHz and with beam switching ability of up to 30° in the elevation plane. The direction of the main beam of the single element antenna in the MIMO is steered over the entire bandwidth through introducing a 3D printed walls with different heights on the side of the 3D printed radiating antenna. Unlike all other available beam steering techniques; the proposed wall is not only able to change the direction of the beam of the antenna, but also it is able to increase the overall directivity and gain of the proposed antenna and MIMO at the same time over the entire bandwidth.
