摘要

本文提出了一种适用于3.5 GHz MIMO天线移动应用的叠加寄生贴片。寄生贴片被放置在散热器贴片的顶部。MIMO天线由四个矩形天线单元组成，尺寸为fr4，尺寸为$\mathbf{156\ x\ 40} \mathbf{mm}^{2}$，堆叠MIMO天线的总厚度为3.84 mm。寄生贴片的存在有助于提高低互耦MIMO天线的阻抗带宽、驻波比和s参数等性能。从3.3949 GHz到3.7214 GHz (326.5MHz)，阻抗带宽提高了42.57%。在阻抗带宽谱上，VSWR小于2，在3.5 GHz时，VSWR最低为1.11。此外，该叠置MIMO天线在3.5 GHz工作频率下也具有良好的ECC(小于0.02)和分集增益(大于9.98)。

Bandwidth Enhancement using Stacked Patch MIMO Antenna with Low Mutual Coupling for 3.5 GHz

In this paper, this proposed stacked parasitic patch is presented for 3.5 GHz MIMO antenna mobile application. The parasitic patch is placed on top of the radiator patch. The MIMO antenna is composed of four rectangular antenna elements on a compact size of FR 4 with a $\mathbf{156\ x\ 40} \mathbf{mm}^{2}$ and total thickness of the stacked MIMO antenna is 3.84 mm. The presence of parasitic patch contributes to improve the performance of MIMO antenna with low mutual coupling including impedance bandwidth, VSWR and S-parameter. There is a 42.57% improvement of impedance bandwidth through 3.3949 GHz to 3.7214 GHz (326.5MHz). VSWR values less than 2 along impedance bandwidth spectrum and the lowest VSWR is 1.11 at 3.5 GHz. In addition, this proposed stacked MIMO antenna also has good ECC (less than 0.02) and diversity gain (more than 9.98) at an operating frequency of 3.5 GHz.
