ANTENNA CORE AND METHOD FOR PRODUCING AN ANTENNA CORE
摘要
The invention relates to an antenna core that comprises a flexible stack of a plurality of oblong soft-magnetic strips (1) consisting of an amorphous or nanocrystalline alloy. The strips of said antenna core are separated from one another by an electrically insulating film (2) 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.
