Wireless communication antenna and mobile device including the same

A mobile device, comprising:

• a wireless communication antenna comprising coil portions each spaced apart from the other, the coil portions having a solenoid shape and a magnetic body as a core;
• and
• a cover having at least one slit and covering the wireless communication antenna,
• wherein the wireless communication antenna is disposed such that a portion of a magnetic field generated by the wireless communication antenna passes through the at least one slit, and
• wherein the at least one slit comprises a first slit and a second slit, and the wireless communication antenna is disposed on an internal portion of the cover between the first slit and the second slit.

A mobile device, comprising:

• an antenna formed around a magnetic body, the antenna having coil portions each spaced apart and connected to the other;
• each of the coil portions is formed on a film substrate;
• and
• a metallic cover disposed over the antenna, the metallic cover having slits,
• wherein each of the coil portions of the antenna radiate magnetic fields and the magnetic fields of each of the coil portions overlap to radiate magnetic stripe data,
• wherein the antenna is disposed such that a portion of the magnetic fields passes through the slits, and
• wherein the slits comprises a first slit and a second slit, and the antenna is disposed on an internal portion of the metallic cover between the first slit and the second slit.

A wireless communication antenna, comprising:

• a magnetic body;
• coil portions having a solenoid shape and the magnetic body as a core, spaced apart from each other, and connected to each other in series, wherein magnetic fields, radiated by the coil portions, overlap each other, and each of the coil portions comprises:
• a first wiring portion disposed on a first surface of the magnetic body;
• a second wiring portion disposed on a second surface of the magnetic body;
• and
• conductive vias interconnecting the first wiring portion and the second wiring portion,
• wherein the wireless communication antenna, covered by a cover having at least one slit, is disposed such that a portion of the magnetic fields passes through the at least one slit, and
• wherein the wireless communication antenna is disposed such that a wound shaft of the coil portions is perpendicular to the at least one slit.
