| 摘 要： | 研究了一种微带线馈电的双倒L形双频MIMO印刷天线结构,通过在倒L单极子结构上加载一条倒L形地板枝节,实现了天线的双频特性;通过在天线单元之间加载一条T形去耦枝节,有效提高了天线单元之间的隔离度。实验结果表明,天线在S11≤-10 dB时,工作频段分别为2.39~2.53 GHz和4.92~6.15 GHz,相对带宽分别为5.7%和22.2%,工作频段内隔离度均大于18 dB。此外,天线整体辐射特性较好,结构简单并易于制作,可应用于WLAN无线通信系统。

| Abstract: | A printed dual-band MIMO antenna was investigated,which has double-inverted L-shaped structure with microstrip line feed.The dual-band of the antenna were achieved using an inverted L-shaped floor branch on an inverted L monopole structure.The isolation was effectively improved by loading a T-shaped decoupling branch between the antenna elements.The experimental results show that at S11≤-10 dB the operating bands are 2.39-2.53 GHz and 4.92-6.15 GHz with relative bandwidth of 5.7%and 22.2%respectively.The isolation in the working band is larger than 18 dB.The antenna also excel in overall radiation characteristics,simple structure and easy fabrication,which merits their applications in WLAN wireless communication system. |
