Wind Influence of Air Wire Antenna Suspended from Drone

In this paper, we propose an antenna system of high frequency (HF) antenna suspended from a drone. By using drone as a relay machine, it is possible to suppress the interference wave from the earth for communication at about 100 m above the earth, thus the communication over long distance utilizing low power can be established. The problem of decreasing in gain due to wind influence is solved by reducing the size of the antenna and adding a matching circuit.
