MAGNETIC ANTENNA Russian patent published in 1997 - IPC

FIELD: ratio engineering; receiving antennas for special-purpose receiving units, such as mine communication system equipment. SUBSTANCE: antenna has current transformer with leads of each transformer primary winding connected through one lead to antenna capacitor and through other lead, to antenna coil forming m (m=2,3,4...) series-parallel circuits; transformer secondary winding is output winding with capacitor connected in parallel to its leads. EFFECT: improved selectivity and sensitivity of antenna due to summing up signals coming from magnetic antennas. 3 dwg
