Abstract
This paper presents a novel virtual array for FANETs wireless links at the frequency of 2.4 GHz. The proposed design considers a 3D random topology for eight nodes of a FANET. The main novelty is that each node is now composed of a rectangular patch antenna mounted on a realistic aircraft structure. This permits us to have a more precise performance of the radiation pattern. The optimum node locations compensate for the interference caused by the aircraft structures. The design problem is formulated to optimize the node locations by utilizing the Differential Evolution method for Multi-objective Optimization. Simulation results are provided in directivity and sidelobe level and compared concerning the most common antenna arrays topologies such as linear, circular, rectangular, and cubic array. The maximum aperture size of the virtual array is 20λ for providing a directivity value of 13.6 dBi with a side lobe level of 7.82dBi.
