This paper presents a compact configured 5G dual-band MIMO loop antenna system for laptop computers. The antenna system consists of two identical 95 × 2 mm2 four-antenna units that are arranged on the top edge of the display ground plane and are 10 mm away from the left and right sides. The four-antenna unit, each being a two-dimensional loop antenna of the same structure and size, are constructed on the on a 0.4 mm-thick FR4 substrate. The loop antenna with only 23 × 2 mm2 size is composed of a T-shaped feed-in section and a double short-circuit loop. In addition, the four loop antennas are arranged in the same direction and side by side with only 1 mm space to form a high-isolation four-antenna unit. The two sets of four-antenna units can cover 5G dual-band operation at 3300–3600 MHz and 4800–5000 MHz. The measured isolation between eight antennas is all better than 15 dB, the measured antenna efficiency is between 35% and 62%, and the measured envelop correlation coefficient ECC calculated from the electric-field radiation pattern is all less than 0.2. This compactly configured eight-antenna system is only 2 mm high in profile, making it ideal for use in 5G laptops with a high screen-to-body ratio.

紧凑配置的 5G 双频 MIMO 环形天线系统

本文提出了一种用于笔记本电脑的紧凑配置 5G 双频 MIMO 环形天线系统。天线系统由两个相同的95×2 mm 2四天线单元组成,布置在显示屏地平面的顶部边缘,距离左右两侧各10 mm。四天线单元均是结构和尺寸相同的二维环形天线,构建在0.4毫米厚的FR4基板上。仅23×2毫米2的环形天线尺寸由T形馈入段和双短路回路组成。此外,四根环形天线同向并排排列,间距仅为1毫米,形成高隔离度的四天线单元。两组四天线单元可覆盖3300-3600 MHz和4800-5000 MHz的5G双频运行。实测8个天线之间的隔离度均优于15 dB,实测天线效率在35%至62%之间,实测电场辐射方向图计算的包络相关系数ECC均小于0.2。这款配置紧凑的八天线系统高度仅为 2 毫米,非常适合用于高屏占比的 5G 笔记本电脑。
