A recent market prediction is that 5G Fixed Wireless Access (FWA) will more than double over the next five years and trials at the same period in London suggest promising results. However, the shift to 5G FWA has raised a new set of research challenges in relation to speed of deployment and re-deployment, coverage, power consumption, end user mobility and last mile connectivity, to name just a few, because of the much higher expectations. A recent review reveals that key 5G Physical Layer technologies that will enable wide mobile and FWA have not kept up pace. In response to some of those research challenges, this paper presents the design of a 5G Multiple Input Multiple Output (MIMO) Antenna that is mounted on a tethered aerostat, and the combination of which serves as a 5G FWA aerial station. The antenna design features several novelties and the aerial station can provide last mile connectivity to a wide coverage footprint, with moderate power consumption and operating at high speeds. Both the evaluation of the antenna performance using several key performance indicators and the validation of the aerial station as a 5G FWA in a wireless sensor network (WSN) proof-of-concept application reveal efficiency gains.

最近的市场预测是，5G 固定无线接入 (FWA) 将在未来五年内翻一番以上，同期在伦敦进行的试验表明结果很有希望。然而，向 5G FWA 的转变在部署和重新部署速度、覆盖范围、功耗、终端用户移动性和最后一英里连接等方面提出了一系列新的研究挑战，仅举几例，因为期望。最近的一项审查显示，支持广泛移动和 FWA 的关键 5G 物理层技术没有跟上步伐。为了应对其中的一些研究挑战，本文介绍了安装在系留浮空器上的 5G 多输入多输出 (MIMO) 天线的设计，其组合可用作 5G FWA 空中站。天线设计具有多项新颖性，空中站可以提供最后一英里连接到广泛的覆盖范围，具有中等功耗和高速运行。使用几个关键性能指标评估天线性能以及在无线传感器网络 (WSN) 概念验证应用中验证空中站作为 5G FWA 都显示了效率提升。
