Antenna device and ic card having the same

An IC card comprising:

• an antenna device;
• and
• an IC module,
• wherein the antenna device comprises:
• a substrate;
• and
• a first coil pattern provided on one surface of the substrate,
• wherein the first coil pattern has a first winding part, a second winding part, and a third winding part,
• wherein the first winding part is wound in a plurality of turns and has an outer peripheral end being opened and an inner peripheral end connected to an outer peripheral end of the second winding part,
• wherein the second winding part is wound in a plurality of turns and has an inner peripheral end connected to an outer peripheral end of the third winding part,
• wherein the third winding part is wound in a plurality of turns and has an inner peripheral end being opened,
• wherein each turn of the second winding part has a first partial winding part wound concentrically with the third winding part and a second partial winding part protruding radially outward from the first partial winding part and wound about a center axis positioned between the first partial winding part and the first winding part, and
• wherein the IC module overlaps the second partial winding part of the second winding part.
