ABSTRACT In this paper, a reduced mutual coupling dual-band multiple-input-multiple-output (MIMO) antenna is reported. A thin rectangular slot is incorporated into an unlicensed 5.2 GHz band rectangular patch antenna (RPA) to excite another industrial, scientific and medical (ISM) 2.4 GHz band. In the MIMO configuration, antennas are closely placed at a distance of and the mutual coupling between antenna elements is suppressed by incorporating a dual-band electronics-bandgap (EBG) structure. A mushroom kind of EBG arrangement with two different square-shaped plates on the top and the bottom of the EBG is done to exhibit dual-band rejection characteristics. MIMO communication parameters, envelope correlation coefficient (ECC), diversity gain (DG), and multiplexing efficiency ( ) are calculated exhibiting excellent performance of the proposed antenna. Prototype of the antenna is fabricated and good agreement is found amongst simulation and measured results.

电子带隙集成低互耦双频MIMO天线

摘要 在本文中，报告了一种减少互耦双频多输入多输出 (MIMO) 天线。一个细长的矩形槽被整合到一个未经许可的 5.2 GHz 频段矩形贴片天线 (RPA) 中，以激发另一个工业、科学和医疗 (ISM) 2.4 GHz 频段。在 MIMO 配置中，天线被紧密地放置在距离 10 的位置，并且通过结合双频带电子带隙 (EBG) 结构来抑制天线元件之间的相互耦合。在 EBG 的顶部和底部具有两个不同的方形板的蘑菇型 EBG 布置是为了表现出双频带抑制特性。MIMO通信参数、包络相关系数（ECC）、分集增益（DG）、和多路复用效率 ( ) 的计算表明所提出的天线具有出色的性能。制造了天线的原型，并且在模拟和测量结果之间发现了良好的一致性。
