摘要:研究提出一款紧缩型十二端口MIMO天线系统,该系统主要由8个立体倒F天线及4个倒F天线构成,其中1—4# 天线及5—8#天线的阻抗带宽可以覆盖3300~3600 MHz 的5G通信频段;而9—12# 天线主要是补充覆盖4800~5000 MHz 的5G通信频段。该MIMO天线系统的低频段与高频段的隔离度分别高于12 dB和19 dB,同时该系统在低频与高频段均具有较高的增益以及辐射效率。
Abstract: A compact 12-port MIMO antenna system is proposed. This system consists of eight stereoscopic inverted F antenna and four inverted F antenna : The 1—4# antenna element and 5—8# antenna element are mainly used for 5G communication and the impedance bandwidth can cover 3300~3600 MHz. The 9—12# antenna element is a supplement to mainly cover the 5G communication spectrum of 4800~5000 MHz. The isolations of the low band and high band of this MIMO antenna system are higher than 12 dB and 19 dB respectively. Moreover, this system has higher gain and radiation efficiency at low band and high band.
