Near field communication package and portable device including the same

A method of a communication in a smart phone, comprising:

• storing data in a secure storage device in a near field communication (NFC) package embedded in the smart phone;
• providing, by an NFC controller in the NFC package embedded in the smart phone, data stored in the secure storage device to a first external terminal by performing an NFC communication using an NFC antenna in an NFC mode;
• and
• providing, by the NFC controller in the NFC package, the data stored in the secure storage device to a second external terminal by performing a magnetic secure transmission (MST) communication using an MST antenna in an MST mode,
• wherein the secure storage device is a secure element having an electronic tamper-resistant function and a mechanical tamper-resistant function,
• wherein the NFC controller includes:
• a transmitting block having first and second transmitting terminals connected to the NFC antenna and the MST antenna, wherein the transmitting block is configured to drive the NFC antenna connected to the first and second transmitting terminals to perform the NFC communication in the NFC mode, and to drive the MST antenna connected to the first and second transmitting terminals to perform the MST communication in the MST mode,
• wherein the NFC antenna includes a first loop coil, and the MST antenna includes a second loop coil,
• wherein the first and second transmitting terminals of the transmitting block are connected to the first loop coil of the NFC antenna via a first impedance matching circuit, and are directly connected to the second loop coil of the MST antenna,
• wherein the transmitting block is configured to perform an NFC communication using the first loop coil in the NFC mode, and perform an MST communication using the second loop coil in the MST mode,
• wherein the first impedance matching circuit includes:
• a first capacitor connected between a first end of the first loop coil and a second end of the first loop coil;
• a second capacitor connected between the first end of the first loop coil and the first transmitting terminal of the transmitting block;
• and
• a third capacitor connected between the second end of the first loop coil and the second transmitting terminal of the transmitting block, and
• wherein the second loop coil includes a first loop configured to form a current path in a counterclockwise direction, and a second loop adjacent to the first loop configured to form a current path in a clockwise direction.
