Abstract (en)
[origin: EP2139011A1] Disclosed is a method for producing a magnetic core for antenna wherein thin metal strips are laminated. This method for producing a magnetic core for antenna is characterized in that a metal thin band is processed into strips having a width of the aimed magnetic core for antenna, then the thin strips are stacked through a resin layer to form a laminate, and after that the laminate is cut into a length of the aimed magnetic core for antenna.
