摘要
5G通信相对4G优势是全方位的,特别是毫米波、小基站、massive MIMO、全双工、波束成形等5大技术,应用领域宽广如物联网、车联网、VR等,是面向2020年以后的通信需求的新一代通信系统。而大规模天线是未来天线的发展趋势,5G是无线关键技术之一,是5G通信的"高速公路",但利弊共存,且其测试也具有挑战性。文章对5G通信与massive MIMO天线技术进行了研究。
Compared with 4G communication,5G has the overall advantage,especially,the five technologies which include millimeter wave,micro base station,massive MIMO,full duplex and beam forming.5G communication has broad application fields such as IoT,IoV,VR,etc,and it has become a new generation telecommunication system for 2020 year and later.The massive MIMO antenna is the development trend in the future,5G is the one of the key technologies,as well as the highway of 5G communication,and tendency of future base station antenna.But its advantages and disadvantages coexist,and its testing is also challenging.
