摘要

为了满足人口密集的移动网络对高数据速率日益增长的需求，开发紧凑高效的天线设计是实现5G和6G技术的必要条件。MIMO天线技术的使用在减少网络拥塞方面显示出前景。本研究调查了石墨烯在太赫兹（THz）天线应用中的应用带来的好处。这项研究最终开发了一种独特的多波段双石墨烯带状线缝隙贴片MIMO （DGSSP-MIMO）天线，该天线工作在三个频率：4.71太赫兹、8.55太赫兹和9太赫兹。当添加石墨烯时，反射响应（S11）下降到−37.2783 dB，表明信号被很好地包含在天线内，尽管增益比未添加石墨烯的天线（12.94 dB）低8.46 dB。当使用机器学习优化技术对参数进行调优时，我们获得了非常好的结果（R2 = 0.976822）。这表明石墨烯可以用来制造高性能的太赫兹天线。DGSSP-MIMO天线具有多频段响应特性，在无线通信和6G技术中有着广泛的应用。

Design of machine learning optimized THz MIMO antenna for next-generation wireless communication systems

To meet the growing demand for high data rates in densely populated mobile networks, the development of compact and efficient antenna designs is necessary for the implementation of 5G and 6G technologies. The use of MIMO antenna technology shows promises in reducing network congestion. The present study investigates the benefits associated with the utilization of graphene in terahertz (THz) antenna applications. This investigation culminates in the development of a distinctive multiband Double Graphene Stripline Slot Patch – MIMO (DGSSP-MIMO) antenna, which operates at three frequencies: 4.71 THz, 8.55 THz, and 9 THz. When graphene was added, the reflection response (S11) decreased to −37.2783 dB, indicating that the signal was well contained within the antenna, though the gain was 8.46 dB lower than that of antennas without graphene (12.94 dB). We obtained very good results (R² = 0.976822) when tuning the parameters using machine learning optimization techniques. This demonstrates that graphene could be used to create high-performance terahertz antennas. The DGSSP-MIMO antenna, with its multiband response, has a wide range of applications in wireless communication and 6G technology.
