Claim Text:
1. A magnetic antenna for transmitting and receiving information using an electromagnetic induction method, comprising a central core formed of a magnetic material and a non-magnetic material, a coil-shaped electrode material disposed outside of and wound around the magnetic material and the non-magnetic material of the central core, and an insulating layer formed on at least one outside surface of the core on which the coil-shaped electrode material is provided, in which the magnetic material is separated into two or more parts through the non-magnetic material when viewed in a section of the core which is perpendicular to a magnetic flux passing therethrough, wherein the coil-shaped electrode material is oriented relative to the magnetic material and the non-magnetic material such that each coil of the electrode material is concurrently wound around both the magnetic material and the non-magnetic material.
