本文设想了一种用于超宽带频率范围应用的紧凑型两端口 MIMO 天线的设计。本文介绍了部分接地的概念，最终有助于实现更宽的频率带宽。拟议的 MIMO 天线设计在称为 FR4 环氧树脂的基板上。位于接地层的贴片是用铜制成的。所提出的MIMO天线尺寸为24mm×24mm×1.6mm。放置在天线顶部的贴片是通过放置圆形槽创建的，最终导致稳定的电流和更高的反射系数。该天线在8.6 GHz谐振频率下实现了-42.62 dB的反射系数。该天线实现了3GHz至12GHz的−10dB带宽，覆盖了整个免授权超宽带频率范围。该天线在 10.6 GHz 时可实现 2.6 dBi 的最大增益。天线的辐射效率为95.21%。这项工作完成了双端口天线的设计，该天线可以获得更高的反射系数和更宽的带宽。天线可以借助环形贴片和部分接地来实现这些目的。
This paper contemplates the designing of a compact two-port MIMO antenna for ultra-wideband frequency range applications. This paper introduces the concept of partial ground which eventually helps in achieving wider frequency bandwidth. The proposed MIMO antenna is designed over a substrate called FR4 epoxy. The patch located in the ground plane was fabricated using copper. The proposed MIMO antenna dimensions are 24mm×24mm×1.6mm. Patch placed at the top of the antenna is created by placing circular slots which eventually lead to steady current and higher reflection coefficient. The antenna achieves a reflection coefficient of −42.62 dB at the resonating frequency of 8.6 GHz. The antenna achieves the −10dB bandwidth ranging from 3 GHz to 12 GHz which covers the whole unlicensed ultra-wideband frequency range. The antenna achieves a maximum gain of 2.6 dBi at 10.6 GHz. Radiation efficiency of the antenna is 95.21%. This work concludes the designing of a two-port antenna that can attain a higher reflection coefficient with a wider bandwidth. The antenna can achieve these purposes with the help of annular patches and partial ground.
