FIELD: antenna equipment.
SUBSTANCE: invention relates to the antenna equipment. Antenna comprises matching device in the form of transformer consisting of primary and secondary windings, radiating vibrator in form of flat or volumetric conducting body, connected to secondary winding and located in magnetic field of matching transformer. At the same time, near the secondary winding of the transformer there is a movable capacitive element connected galvanically at any point to the transformer, and a mechanism of manual or automatic movement of the capacitive element relative to the secondary winding and fixation in the selected position.
EFFECT: enabling smooth tuning of the operating frequency of the antenna and a device for connecting the transceiver to inductive communication lines in a wide range of radio waves and, as a result, possibility of compensation of influence of external objects having capacitance and switching to other frequency channels of reception-transmission of radio signals.
