FIELD: physics.
SUBSTANCE: object of invention is antenna system with kilometre, hectometre or decameter surface waves, containing at least one antenna (24), electrically short in vertical plane, with vertical or elliptical polarization and emitting radiation, wherein said antenna (24) is connected to conductive medium (28), having a substantially horizontal surface. Antenna system (22) also comprises at least one conductive parasite component (30) extending in a direction substantially parallel to surface of conductive medium (28) electrically isolated from each antenna (24) and located near at least one antenna (24) so as to be able to emit due to current induced by said radiation of said antenna (24). Invention allows combining the resultant of each radiating element in order to control the beam pattern in the vertical plane.
EFFECT: invention reduces ionospheric radiation, reduces antenna dimensions in vertical direction and easily changes bandwidth.
