## Abstract

The invention relates to antenna technology. An antenna comprises a matching device in the form of a transformer consisting of a primary winding and a secondary winding, a radiating vibrator in the form of a planar or three-dimensional conducting body, the radiating vibrator being connected to the secondary winding and arranged in a magnetic field of the matching transformer. Reactive discrete components (of capacitance, inductance) are galvanically connected within a gap to the matching transformer using controlled relays, or capacitive elements arranged alongside turns of the secondary winding of the transformer are connected using relays to one of the points of the transformer. The technical result is the capability of rapid retuning of the working frequency of the antenna in a broad range of frequencies and, consequently, the capability of compensating for the influence of external objects which have capacitance, and switching to other radio signal reception and transmission frequency channels.
