Reader coil antenna, and non-contacting type card identification system using the same

A non-contacting type card identification system using a reader coil antenna, comprising:

• a reader coil antenna which forms a magnetic field from a signal applied to flow in an single direction;
• a card reader to transmit an operating signal through the reader coil antenna, and decode an input signal from a non-contacting type card;
• and
• a control unit to decide identification of the non-contacting type card according to the decoded signal,
• wherein the reader coil antenna comprises:
• an outer coil forming a predetermined loop, and forming a magnetic field by receiving a current;
• and
• at least one inner coil disposed inside the loop of the outer coil, wherein said at least one inner coil generates a constructive interference in a direction of the magnetic field formed by the outer coil, and
• wherein the outer coil and the inner coil are mounted on a printed circuit board, and wherein one side of the printed circuit board comprises a magnetic inducing layer coated with a non-conductive magnetic material.
