【摘要】 本文提出了一种利用正交模式解耦的双天线结构,在两个天线近距离布局的情况下可实现20 dB以上的隔离度。基于正交模式对,本文设计了一种工作于5 GHz频段的8×8 MIMO手机天线,该方案可以将MIMO天线占用的区域减少一半。此外,本文还进一步分析了在实际应用环境中人手对该天线的影响。仿真和测试结果表明,该天线在3.4-3.6 GHz实现VSWR小于3,所有端口之间的隔离度大于17dB,包络相关系数小于0.07。更多还原

【Abstract】 This paper proposes a dual-antenna structure decoupled by orthogonal-mode approach.More than 20 dB isolation is achieved despite the two antennas are closely spaced.Based on the orthogonal-mode pairs,a 8×8 MIMO mobile phone antenna operating at 5G band is designed,which can reduce half of the occupied locations in the mobile phone.Moreover,the effects in the practical application environment with user’s hand is analyzed.Both the simulation and test results show that,the proposed antenna can achieve VSWRs<3, isolations> 17 dB and envelope correlation coefficients <0.07 in 3.4～3.6 GHz.更多还原
