Abstract
The drone comprises M antennas, with in particular two offset antennas located symmetrically at the ends of two arms for the connection to the propulsion units (24), and a ventral antenna under the drone body. The radio transmission is operated simultaneously on N similar RF channels, with 2≤N<M. An antenna switching circuit couples selectively each of the N RF channels to N antennas out of the M antennas according to a plurality of different coupling schemes, dynamically through a piloting logic selecting one of the coupling schemes. The selection is operated as a function of a signal delivered by the drone-borne microprocessor, as a function of the flight and signal transmission conditions, determined at a given instant.
