摘要

提出了一种用于5G移动通信设备的紧凑型双频8 × 8多输入多输出(MIMO)天线阵列，其工作频率低于6ghz。跨工作频带的阻抗带宽分别接近n77/78/79频带的带宽规格。在n77/78/79频段，测得的峰值增益和天线效率分别接近3.0 dBi / 80%和3.8 dBi / 50%。并且，在该MIMO天线阵列的工作频带上，测量到的包络相关系数(ECC)小于0.2。

A Compact Hybrid Antenna for 5G Sub-6GHz MIMO Operation

A compact dual-band 8 × 8 multi-input multi-output (MIMO) antenna array for a 5G mobile communication device is proposed to have sub-6GHz operation. The impedance bandwidths across the operating bands approach the bandwidth specification of the n77/78/79 bands, respectively. The measured peak gains and antenna efficiencies are close to 3.0 dBi / 80 % and 3.8 dBi / 50 % across n77/78/79 bands, respectively. And, the measured envelope correlation coefficient (ECC) is less than 0.2 across the operating bands for this MIMO antenna array.
