摘要

提出了一种双端口双频多输入多输出(MIMO)天线阵列，该天线阵列由两个印刷圆形单极子天线组成。仿真数据表明，天线- 10db阻抗带宽分别为2.3 GHz ~ 2.8 GHz和3.37 GHz ~ 3.72 GHz。通过微带中和线与地平面中的存根连接天线，增强了天线元件之间的隔离。相互耦合小于-15 dB，元件间间距为自由空间波长的0.092倍。该天线的最大增益为3.66 dBi，整个带宽的包络相关系数≤0.06211。

Low Mutual Coupling Dual-port Dual-band MIMO Antenna Array for Mobile Terminal

A dual-port dual-band multiple-input-multiple-output (MIMO) antenna array comprises of two printed circular monopole antennas is presented. Based on simulated data, the -10 dB impedance bandwidth of the antenna is noted from 2.3 GHz to 2.8 GHz and 3.37 GHz to 3.72 GHz. The isolation between the antenna elements is enhanced by connecting antennas through a microstrip neutralisation line along with a stub in the ground plane. Mutual coupling is found to be below -15 dB with an inter-element spacing of 0.092 times the free-space wavelength at 2.3 GHz. The maximum gain of the antenna is noted to be 3.66 dBi with an envelope correlation coefficient ≤ 0.06211 in its entire bandwidth.
