In this paper, it investigates the effective use of multiple four-rotor drones as an aerial antenna array which offers ground users wireless service. In addition a novel framework for deploying and operating a drone based antenna array system whose elements are single-antenna drones is proposed to minimise air transport time for communicating with ground operators. The use of UAVs as data relays is a promise both for the delivery of on-demand connectivity and for the provision of public safety serves as well as for the recovery of communication infrastructure defects caused by natural disasters. Firstly, by optimising Drone Spacing within the array, the antenna array gain is optimised. In this case, the drone space optimization problem is resolved by resolving successive, disturbed problems with convex optimization using disturbance techniques. The second step consists of the optimal location of the drones at the array centre so that the service time is minimised for each ground user. The simulation results shows that, compared to a single drone that uses the same power as the array, the proposed approach can considerably reduce service times for ground users. The results also show that the spectral efficiency of the network can be improved by 78 percent while the drone array system is utilised. In comparison with a fixed array case in which the same number of drones form a fixed, uniform antenna array, the proposed method can significantly reduce ground users' time of service.
