RESONANT MULTI-BAND ANTENNA Russian patent published in 2019 - IPC H01Q9/04 

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 to the matching transformer in the gap galvanically connected reactive discrete components (capacitance, inductance) or by means of relays to one of the points of the transformer there are connected capacitive elements located near coils of the secondary coil of the transformer.

EFFECT: possibility of rapid reconstruction of its operating frequency in a wide frequency range and, as a result, possibility of compensation of influence of external objects having capacity, and switching to other frequency channels of reception-transmission of radio signals.
