摘要

提出了一种新型紧凑型宽带多输入多输出(MIMO)天线。MIMO天线包括连接在两个对称开槽d形单极子之间的宽带中和线和切入到接地面顶部的缺陷接地结构。采用宽带中和线作为去耦技术,在天线输入端采用缺陷地平面作为阻抗匹配元件,MIMO天线的- 10dB阻抗带宽达到50.42% (8.90 ~ 14.90 GHz),隔离度优于20 dB。

A Wideband Slotted D-Shaped Monopole MIMO Antenna With Triple Branch Neutralization Line
A novel compact wideband multiple-input-multiple-output (MIMO) antenna is presented in this paper. The MIMO antenna comprises of a wideband neutralization line connected in between two symmetric slotted D-shaped monopoles and a defected ground structure which is cut into the top of the ground plane. With the introduction of wideband neutralization line as a decoupling technique and defected ground plane as an impedance matching element at the input ports of both the antennas, the proposed MIMO antenna achieves −10dB impedance bandwidth of 50.42% (8.90-14.90 GHz) with isolation better than 20 dB.
