To achieve this, we utilized the 3GPP 36.814 base station antenna gain pattern model and the HTZ Communications simulation tool from ATDI to analyze the reference signal received power, representing communication quality, based on the altitude of the UAV and the tilt of the base station antenna. The analysis results indicate that the current ground-based stations, located on the ground, meet the coverage and communication quality requirements for the terrestrial environment. However, issues such as coverage gaps, shadow areas, and signal strength inadequacies arise when UAVs are positioned in the airspace. Particularly noteworthy is the fact that considering the maximum flight altitude of low-altitude UAVs is 6,000 meters, additional downward tilt of the base station antennas could exacerbate issues such as insufficient aerial coverage, shadow areas, and poor communication quality. Therefore, further research on aerial networks is deemed necessary." }
