BROADBAND VLF-MF RANGE RECEIVING FERRITE ANTENNA Russian patent published in 2012 - IPC H01Q7/00 

FIELD: electricity.

SUBSTANCE: N -boosting transformers (secondary windings whereof are connected in series) are connected to the broad coil of the broadband receiving ferrite antenna via N>1 of its parallel terminals located along the coil. According to the second version the broad coil is designed to be composed of N>1 more narrow coils each equipped with a boosting transformer, the secondary windings of the N transformers connected in series. The antenna winding inter-coil capacity is reduced both due to the transformers secondary windings designed to be one-layered and to distribution of this capacity between the transformers.

EFFECT: receiving ferrite antenna broadbandness enhancement.
