| 摘 要： | 提出一种应用于5G智能手机中结构紧凑的16单元多频段多输入多输出(MIMO)天线阵列。该多天线系统由8个紧凑天线阵列对组成，为了预留2G/3G/4G天线的布局空间，这8个天线阵列印刷在智能手机的两侧边上。每个天线阵列对由2个紧凑的间隙耦合环路天线组成，分别布置在系统板的上、下两侧；其中上侧天线工作在LTE band 46(5 150~5 925 MHz)，下侧天线覆盖LTE band 42/43(3 400~3 800 MHz)。测试结果表明该天线阵列具有良好的阻抗匹配和隔离性能。同时还对MIMO一些包络相关系数进行了研究分析。最后研究了人手和头对整个天线性能的影响，仿真结果表明，在日常各种使用情况下，该天线阵列也具有良好的辐射特性。

| Abstract: | A compact 16-port multiband antenna array for massive Multiple-Input Multiple-Output (MIMO) applications in future 5G smartphones is proposed. The multi-antenna system consists of eight pairs of compact antenna arrays. In order to reserve the local space of the 2G/3G/4G antennas, the eight pairs of antenna arrays are printed on both sides of the smartphone. Each antenna array pair consists of two compact gap-coupled antennas, arranged on the upper and lower sides of the system board. The upper antenna operates in LTE band 46(5 150-5 925 MHz), and lower antenna covers LTE band 42/43(3 400- 3 800 MHz). Test results show that the antenna array has good impedance matching and isolation performance. In addition, this paper also studies and analyzes some characteristic parameters of MIMO. Finally, the effects of hand and head for antenna are studied. The results of simulation and measurement show that the antenna array has good radiation characteristics and MIMO performance. |
