Abstract
An antenna arrangement comprises a casing comprising a flange and a collar extending upwards from the flange. A magnetic loop antenna coil covers an outer surface of at least one of the flange and the collar at least partly. A magnetic material layer is arranged between the magnetic loop antenna coil and the outer surface of the flange and the collar to guide the magnetic flux generated by the magnetic loop antenna coil, the magnetic material layer covering both the flange and the collar at least partly.
