Abstract

A highly bendable antenna core (8) which is highly bendable for high-frequency identification systems substantially retains its soft-magnetic properties when bending occurs. The antenna core is produced by using specific amorphous or nanocrystalline alloys having a very low magnetostriction value. The antenna core (8) is embodied in the form of a laminate with/or without insulating layers placed therebetween. An antenna can be provided with one such antenna core.
