  • Patent number: 7818874
    Abstract: An antenna core comprises a flexible stack of a plurality of oblong soft-magnetic strips consisting of an amorphous or nanocrystalline alloy. The strips of said antenna core are separated from one another by an electrically insulating film each. The amorphous or nanocrystalline alloy has a magnetostriction value lambdas in the range of +4<.>10<?6> to ?4<.>10<?6> and a linear BH loop. The coefficient of induction L of the antenna core changes at 60 kHz at a center distortion by 25% of its length by less than 10% and the quality Q of the antenna core is >=10 at 60 kHz.
    Type: Grant
    Filed: July 8, 2009
    Date of Patent: October 26, 2010
