Abstract

In this work, a new prototype of the eight-element MIMO antenna system for 5G communications, internet of things, and networks has been proposed. This system is based on an H-shaped monopole antenna system that offers 200 MHz bandwidth ranges between 3.4-3.6 GHz, and the isolation between any two elements is well below -12 dB without using any decoupling structure. The proposed system is designed on a commercially available 0.8 mm-thick FR4 substrate. One side of the chassis is used to place the radiating elements, while the copper from the other side is being removed to avoid short-circuiting with other components and devices. This also enables space for other systems, sub-systems, and components. A prototype is fabricated and excellent agreement is observed between the experimental and the computed results. It was found that ECC is 0.2 for any two radiating elements which is consistent with the desirable standards, and channel capacity is 38 bps/Hz which is 2.9 times higher than 4 × 4 MIMO configuration. In addition, single hand mode and dual hand mode analysis are conducted to understand the operation of the system under such operations and to identify losses and/or changes in the key performance parameters. Based on the results, the proposed antenna system will find its applications in modern 5G handheld devices and internet of things with healthcare and high rate delivery. Besides that, its design simplicity will make it applicable for mass production to be used in industrial demands.

摘要

在这项工作中，提出了一种用于 5G 通信、物联网和网络的新型八元 MIMO 天线系统原型。该系统基于 H 形单极天线系统，在 3.4-3.6GHz 频段内提供 200MHz 的带宽范围，并且在不使用任何解耦结构的情况下，任意两个元件之间的隔离度低于-12dB。所提出的系统设计在商业上可获得的 0.8 毫米厚的 FR4 基板上。底盘的一侧用于放置辐射元件，而另一侧的铜被去除以避免与其他组件和设备短路。这也为其他系统、子系统和组件留出了空间。制造了一个原型，并且在实验和计算结果之间观察到了极好的一致性。结果发现，任意两个辐射元件的 ECC 为 0.2，这符合理想的标准，信道容量为 38 bps/Hz，比 4×4 MIMO 配置高 2.9 倍。此外，进行了单手握持模式和双手握持模式分析，以了解系统在这些操作下的工作情况，并确定关键性能参数的损耗和/或变化。基于这些结果，所提出的天线系统将在现代 5G 手持设备和物联网中得到应用，包括医疗保健和高速传输。此外，其设计简单性将使其适用于大规模生产，以满足工业需求。
