摘要
基站天线作为移动通信系统的重要组成部分,其性能直接影响移动通信网络的整体功能。随着移动通信网络技术的发展,移动通信基站天线也不断地朝着宽带多频化、小型化以及MIMO天线的方向发展。在即将到来的5G时代,天线与射频模块高度集成,Massive MIMO天线必将成为未来天线的主流。为了进一步了解Massive MIMO天线,通过分析对比基站天线技术演进与发展,研究了Massive MIMO有源天线的特点,最后分析了5G时代天线将面临的挑战以及一些亟待解决的问题。
Base station antenna is the key component of mobile communication systems, whose performance directly affects the overall functions of mobile communication networks. With the development of the mobile communication network technology, the mobile communication base station antenna constantly develops toward the direction of broadband, multiband, miniaturization and MIMO. In the forthcoming 5 G era, the antenna and RF module are highly integrated, and the Massive MIMO antenna is bound to become the mainstream of the future antenna. In order to further investigate MIMO antenna, the evolution and development of the base station antenna technology were analyzed and compared. The characteristics of the active Massive MIMO antenna were addressed. Finally, the challenge and some suspended problems faced by the antenna in 5 G era were analyzed.
