LOW-FREQUENCY FOLDED DIPOLE ANTENNA Russian patent published in 2022 - IPC H01Q1/36 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and serves for emitting electromagnetic oscillations on communication lines of low-frequency radio wave ranges. The technical result is achieved by proposing a low-frequency folded dipole antenna deployed by means of a medium-sized multicopter; the multicopter operates in the hovering mode and is connected with two SPC cables of the length comparable with 0.25λ via an insulator, the lower ends of the SPC cables are connected with the same conductor of an electric counterweight; the counterweight is made in in the form of at least three electrical conductors located and secured on the ground and are radially diverging from the central point of connection thereof; the lower ends of the SPC cables are spaced from the connection point of the conductors of the counterweight to a distance comparable with 0.025λ; the output electrodes of the antenna are the lower end of one main SPC cable and the point of connection of the power source.

EFFECT: expanded working bandwidth.
