Abstract
An antenna arrangement for the inductive transmission of energy has magnetic cores made of a composite material with amorphous or nanocrystalline flakes and a moulded plastic material, so that the magnetic properties suitable for effective energy transmission can be adjusted at the same time as high security against fracture and a small overall height are achieved.
