摘要
本文介绍了一种采用双 Y 形去耦结构的超宽带（UWB）多输入多输出（MIMO）天线，它具有高隔离度和三缺口带。所设计的天线由两个正交放置的单极元件、共面接地和双 Y 形分支组成。为了实现小型化，该天线采用了缺陷衬底结构。通过在辐射贴片和地面上依次开 C 形槽、半圆槽和矩形槽，实现了 3.5 GHz WiMAX、5.25 GHz WLAN 和 7.5 GHz X 波段的三个缺口频带。所提议的天线可在 2.56-12 GHz 范围内工作，并具有 3.31-3.96 GHz、4.58-5.67 GHz 和 6.57-8.16 GHz 三个陷波带。综合所有结果，可以得出结论：所提出的天线在良好辐射、高隔离度（>24 dB）、低水平 ECC（9.99）等方面具有出色的性能，这证明所提出的天线在 UWB-MIMO 系统中具有良好的前景。
CPW-Fed UWB-MIMO Antenna with Triple-band Notched and High Isolation using Double Y-shaped Decoupling Structure
A ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna using double Y-shaped decoupling structure with high isolation and triple notched-band is presented. The designed antenna composed of two orthogonally placed monopole elements, coplanar ground and double Y-shaped branch. The defected substrate structure is used to achieve miniaturization. By slotting successively C-shaped slot, semi-circular slot and rectangular slot on the radiation patch and the ground, achieved three notched bands at 3.5 GHz WiMAX, 5.25 GHz WLAN, and 7.5 GHz X-band. The proposed antenna can operate in range of 2.56-12 GHz with triple notched bands of 3.31-3.96 GHz, 4.58-5.67 GHz and 6.57-8.16 GHz. Considering all the results, it can be concluded that the antenna presented has a great performance in terms of good radiation, high isolation (>24 dB), a low level ECC (<0.01) and a high DG level (>9.99), which proves the presented antenna has good prospect in UWB-MIMO systems.
