【摘要】 本文提出了一种基于复合去耦结构加载的宽带双极化MIMO天线。最终得到的八单元MIMO天线能在46%(1.88GHz～3.01 GHz,VSWR<1.5)的相对带宽内工作,带内隔离度优于18 dB。相较于未添加复合去耦结构的MIMO天线,阻抗带宽从31.6%展宽到46%(VSWR<1.5),带内隔离提升了5.5～15 dB。更多还原

【Abstract】 A broadband dual-polarization MIMO antenna based on composite decoupling structure loading is proposed.The resulting eight-cell MIMO antenna works well within 46%(1.88 GHz～3.01 GHz,VSWR<1.5) of the relative bandwidth with better than 18 dB in-band isolation.Compared with the MIMO antenna without the composite decoupling structure,the impedance bandwidth is widened from 31.6% to 46 %(VSWR<1.5) and the in-band isolation is improved by 5.5～15 dB.更多还原
