A Concept for Far Field Measurements of Large Dimension Antennas in an Open Area Test Site Performed by UAS

Small Unmanned Aerial Systems (UAS), aka `Drones', equipped with apt electromagnetic sensors open a manifold of RF applications. In the context of this paper, UAS are utilized as aerial equipment for open area test site (OATS) measurements at precise 3D locations in the far field of a ground based device under test. The advantages of UAS supported OATS measurements are addressed. The details of a prototype system are described and experimental assessments of the measurement precision are shown.
