FIELD: physics.
SUBSTANCE: invention relates to the receiving magnetic antennas with the omni-directional directivity diagram and can be used in the field conditions in the wearable receiver of the MES staff, etc. for receiving radio commands and alarms. The magnetic antenna comprises two inductance coils formed on the two ferromagnetic cores located at the angle of 90° against each other. Herewith the inductance coils are electrically connected in-phase, and the additionally inserted capacitor is connected parallel to their ends.
EFFECT: obtaining the omni-directional directivity diagram.
