摘要

在该通信中，展示了一种紧凑的印刷cpw馈电双带陷波超宽带(UWB)多输入多输出(MIMO)天线。UWB MIMO天线由两个平面印刷的同单极子PA和PB组成，并在接地面引入了一种改进的Minkowski互补分形结构，以增强MIMO系统的隔离性。通过在共地结构上刻蚀矩形槽和在平面单极子上刻蚀旋转c形槽，分别获得3.3 ～ 3.8 GHz Wi-MAX、3.7 ～ 4.2 GHz c波段和5.15 ～ 5.85 GHz WLAN的陷波带。天线的超宽带带宽范围为3.16 GHz至12 GHz (VSWR $\leq 2)$)。天线散热器和接地面为蚀刻，整体尺寸为26.75 mm $\times$ 37.96 mm。各种仿真结果之间的一致性表明，该天线可以作为各种超宽带通信系统的理想候选天线。仿真结果表明，所提出的超宽带MIMO天线是便携式超宽带和超宽带MIMO系统的理想选择。

A Compact Printed UWB MIMO Monopole Antenna with Modified Complementary Fractal for Isolation Improvement and Triple Band Notch Characteristics

In this communication a compact printed CPW-fed dual band-notched Ultra Wideband (UWB) Multiple Input Multiple Output (MIMO) antenna is exhibited. The UWB MIMO antenna consists of two printed planar identical monopoles PA and PB respectively and a novel modified Minkowski complementary fractal structure is introduced in the ground plane for reinforcing the isolation of the MIMO system. Notch bands encompassing 3.3-3.8 GHz Wi-MAX, 3.7-4.2 GHz C-Band, 5.15-5.85 GHz WLAN are acquired by etching a rectangular slot on the common ground structure and etching rotated C-shaped slots on the planar monopoles respectively. The antenna's Ultra wide bandwidth ranges from 3.16 GHz to 12 GHz (VSWR $\leq 2)$. The radiator and ground plane of the antenna are etched with an overall size of 26.75 mm $\times$ 37.96 mm. The agreement between the various simulation results advocates that the intended antenna can be a worthy candidate for various UWB communication systems. All the simulated results depict that the proposed UWB MIMO antenna is an exceptional candidate for portable UWB as well as UWB MIMO systems.
