设计了一种用于第五代移动通信系统的大规模MIMO天线阵。该天线阵采用8×8矩形排布,天线单元采用缝隙耦合馈电的贴片形式,通过蚀刻在上层地板上的两个正交H型缝隙对辐射贴片分别耦合馈电来实现±45°双线极化特性。所设计的天线阵工作在3. 4 GHz~3. 6 GHz,具有剖面低、结构紧凑、便于与射频前端集成化设计的特点,能够很好地满足下一代移动通信系统对天线阵的设计要求。

A massive MIMO antenna array for the 5G communication system is designed. The antenna array is with 8×8 elements and the rectangular arrangement. The patch fed by coupled slots is chosen as the array element, which realizes ±45° dual-linear polarization by the excitation of two orthogonal H shape aperture slots etched on the upper ground. The designed antenna covering 3.4 GHz~3. 6 GHz frequency band has advantages such as low profile,compact structure and easy integration with RF frontend, which can meet the demand of antenna array for the next generation communication system.
