COMPOSITE COIL PATTERN FOR WIRELESS CHARGING AND MAGNETIC SECURE TRANSMISSION

Provided is a coil pattern designed for achieving different functions of wireless charging and magnetic security transmission (MST) using one coil within a limited area. A composite coil pattern for wireless charging and MST includes a first terminal, a second terminal, a coil pattern connecting the first terminal to the second terminal; and an MST pattern portion connected to the coil through a connection line branching from an outer periphery of the coil, wherein the MST pattern portion is at one side in a direction with respect to the coil, and the MST pattern portion includes a plurality of lines parallel to the direction, and the plurality of lines are lines connecting an inner end located close to the coil to an outer end located far from the coil, and such that the plurality of lines are in serial connection with each other, when an inner end of a first line and an inner end of a second line next to the first line from among the plurality of lines are connected to each other, an outer end of the second line and an outer end of a third line next to the second line may be connected to each other.
