In this editorial, a compact two element Ultra Wide Band Multiple Input Multiple Output (UWB MIMO) antenna with triple-band notch characteristics is presented. A single Two Via Compact Electromagnetic Band Gap (TVC-EBG) structure is used to achieve triple-band notches at WiMAX, WLAN, and X Band. An inverse L-shaped stub is inserted in the ground plane of the antenna to diminish mutual coupling amid antenna elements. Isolation and Envelope Correlation Coefficient (ECC) is less than −15 dB and 0.015, respectively. The diversity properties like Total Active Reflection Coefficient (TARC), Diversity Gain (DG) are less than −10 dB and greater than 9.95 dB respectively. The proposed antenna is designed using a low-cost FR4 substrate with overall dimensions of 21 × 36 × 1.6 mm3.

TVC-EBG结构的紧凑型三带陷波UWB MIMO天线设计

在这篇社论中，介绍了一种具有三频陷波特性的紧凑型二元超宽带多输入多输出 (UWB MIMO) 天线。单个两孔紧凑型电磁带隙 (TVC-EBG) 结构用于在 WiMAX、WLAN 和 X 频段实现三频段陷波。在天线的接地平面中插入倒 L 形短截线，以减少天线元件之间的相互耦合。隔离度和包络相关系数 (ECC) 分别小于 −15 dB 和 0.015。总有源反射系数 (TARC)、分集增益 (DG) 等分集属性分别小于 -10 dB 和大于 9.95 dB。建议的天线使用低成本 FR4 基板设计，整体尺寸为 21 × 36 × 1.6 mm3。
