On the design of HAPs High Throughput and flexible 5G Communication Payloads

This work presents a technical analysis and a proposal of the payload architecture including a 5G antenna design. The analysis covers the comparison with terrestrial networks and satellites, and the frequency bands and service area limitation versus available power and payload technology onboard actual High-Altitude Platforms (HAP). For this, a review of the HAP system capacity and payload requirements is done. Furthermore, the definition of the payload architecture is based on actual and mature state of the art of the technologies and the antenna aperture has dual-band and dual-circular polarization operation capacity.
