紧凑型4×4单元超宽带MIMO缝隙天线设计
Design of Compact 4 × 4 Element Ultra Wide Band MIMO Slot Antenna
摘要
Abstract
In order to realize the miniaturization of the mobile terminal antenna,a compact ultra wideband MIMO ( Multiple Input Multiple Output) antenna with high isolation between cells is proposed. The antenna does not need any decoupling network, and realizes each antenna element through the ladder shaped slot structure. The ladder shaped slot antenna not only reduces the size of the antenna,but also has a directional radiation behavior,thus form-ing a high isolation. The proposed antenna size is 23.7 mm×23.7 mm×0.8 mm. The measurement results show that the proposed multi can produce better radiation properties of ultra wideband MIMO antenna in 3 GHz～10. 9 GHz spectrum( S11=-10 dB) ,impedance isolation is greater than 20 dB,allowable limit envelope correlation coefficient and the channel capacity loss to ensure the good MIMO performance.关键词
