Abstract
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.

Summary
A market analysis report which appeared at the end of 2020 suggests that 5G FWA will grow by 136% by 2026 [1]. The pandemic has exacerbated the fallout from poor or lack of connectivity when access to education, healthcare, business, and important information was only through the Internet as working, studying, and doing business from home became the new normal This has opened up to a plentitude of new fixed wireless aerial solutions which include novel combinations of Unmanned Aerial Vehicles (UAV), Robotics, Artificial intelligent (AI), Biotechnology, Internet of Everything (IoE) to name just a few as Fig. 1 shows as these offer significant advantages over terrestrial systems, i.e. wider coverage footprint, deployment flexibility, terminal mobility and importantly guaranteed last-mile connectivity [4,5,6,7,8]. The rest of this paper is organized as follows: Section II presents related research work in support of the design; section III describes the Model of a 5G Wireless Fixed Aerial Access Station that results from the design and mounting of the 5G MIMO antenna on a tethered aerostat; section IV evaluates the design of the model and in particular the antenna; section V validates the model through proof-of-concept applications in an existing WSN; section VI concludes
