In this article compact multiple input multiple output (MIMO) antenna with triple notch at the ultra-wideband application having two identical monopole antennas is proposed. The two inverted ‘U’ shaped slots are etched on the antenna geometry. The proposed antenna gets notch obtain notch characteristics at three frequencies i.e. 3.51–4.3 (WiMAX), 5.5–5.6 (WLAN) and 8.4–8.8 (X-band applications in UWB spectrum the proposed antenna is designed on FR4 substrate with a compact size of 20 × 34 × 1.6 mm³. The proposed antenna was designed and analysed HFSS 13. An excellent triple notch characteristic is obtained after insertion of Inverted ‘U-shaped compact slot on the radiators. At the centre of the triple notch bands a significant drop in the gain, efficiency of the antenna is seen this indicates a good suppression in the interference of two elements. The simulated and measured results show that the proposed is used for UWB MIMO diversity systems. Thus the proposed antenna two elements are used reduce isolation between channels for ultra wideband MIMO diversity systems.

在本文中，提出了在具有两个相同单极天线的超宽带应用中具有三重陷波的紧凑型多输入多输出（MIMO）天线。将两个倒置的“ U”形槽蚀刻在天线几何形状上。拟议的天线具有陷波特性，可在三个频率上获得陷波特性，即3.51-4.3（WiMAX），5.5-5.6（WLAN）和8.4-8.8（UWB频谱中的X波段应用），拟议天线设计在FR4基板上，尺寸紧凑20×34×1.6毫米³。拟议的天线被设计并分析了HFSS13。在辐射器上插入“ U形”倒置紧凑型槽后，可获得出色的三重陷波特性。在三重陷波频带的中心，增益显着下降，可见天线的效率，这表明对两个元件的干扰有很好的抑制作用。仿真和测量结果表明，该建议用于超宽带MIMO分集系统。因此，所建议的天线两个元件被用于减少超宽带MIMO分集系统的信道之间的隔离。
