Abstract

This study introduces a monopole 4 × 4 Ultra-Wide-Band (UWB) Multiple-Input Multiple-Output (MIMO) antenna system with a novel structure and outstanding performance. The proposed design has triple-notched characteristics due to CSRR etching and a C-shaped curve. The notching occurs in 4.5 GHz, 5.5 GHz, and 8.8 GHz frequencies in the C-band, WLAN band, and satellite network, respectively. Complementary Split-Ring Resonators (CSRR) are etched at the feed line and ground plane, and a C-shaped curve is used to reduce interference between the ultra-wide band and narrowband. The mutual coupling of CSRR enables the MIMO architecture to achieve high isolation and polarisation diversity. With prototype dimensions of (60.4 × 60.4) mm, the proposed antenna design is small. The simulated and measured results show good agreement, indicating the effectiveness of the UWB-MIMO antenna for wireless communication and portable systems.

摘要

本研究介绍了一种具有新颖结构和卓越性能的单极4×4超宽带（UWB）多输入多输出（MIMO）天线系统。所提出的设计由于采用了互补开口环谐振器（CSRR）蚀刻和C形曲线而具有三陷波特性。陷波分别出现在C波段、WLAN频段和卫星网络的4.5 GHz、5.5 GHz和8.8 GHz频率处。在馈线和接地平面蚀刻互补开口环谐振器，并使用C形曲线来减少超宽带和窄带之间的干扰。CSRR的互耦使MIMO架构能够实现高隔离度和极化分集。所提出的天线设计尺寸小，原型尺寸为（60.4×60.4）mm。仿真和测量结果吻合良好，表明该UWB-MIMO天线在无线通信和便携式系统中有效。
