FIELD: radio equipment.
SUBSTANCE: invention relates to radio engineering, particularly to centimeter-wave antenna devices. Essence of the declared solution consists in that the unmanned aerial vehicle (UAV) onboard antenna comprises a vertical reflector arranged in series and linearly on the main metal plate, active vibrator and director, characterized by that main metal plate is installed on pedestal with height of 0.16 λ in upper part of fuselage UAV, where λ is the radio signal wave length, the pedestal metal base is rigidly connected to the UAV metal surface and provides electrical contact, the main metal plate is supplemented with a guide in the form of a metal plate inclined downwards at angle of 55°, which rear edges are rigidly connected to front edges of the main metal plate and provide electric contact, and the front edge of the pedestal base is rigidly connected to the leading edge of the metal plate of the guide and provides electric contact. Known asymmetric antenna "wave channel" is installed on a pedestal of a special shape, the shape and overall dimensions of the underlying surface and the pedestal itself are adapted to solve the task. Working frequencies range is additionally expanded by using an asymmetrical single-stub vibrator as an active vibrator.
EFFECT: increased range of radio communication in conditions of limited dimensions of conducting underlying surface.
