1. A dual mode antenna comprising:
- an insulative sheet;
a loop-shaped wireless communication coil formed on a front surface of the insulative sheet;
a wireless power transmission coil formed inside the loop-shaped wireless communication coil to be electrically disconnected from the loop-shaped wireless communication coil, and formed on the front surface and a rear surface of the insulative sheet, the wireless power transmission coil being electrically connected from each other via a via-hole passing through the insulative sheet to wirelessly transmit or receive power;
a pair of wireless communication coil connection terminals being respectively electrically connected to opposite ends of the loop-shaped wireless communication coil; and
a pair of wireless power transmission coil connection terminals being respectively electrically connected to opposite ends of the wireless power transmission coil; and
a pair of extension patterns configured to electrically connect the pair of wireless power transmission coil connection terminals to the opposite ends of the wireless power transmission coil,wherein a distance between the wireless power transmission coil and the loop-shaped wireless communication coil is greater than a distance between element wires forming either each of the wireless power transmission coil or the loop-shaped wireless communication coil,wherein the wireless power transmission coil formed on the front and rear surfaces of the insulative sheet form a loop, when viewed from the front surface of the insulative sheet, to allow current to flow in a same direction,wherein the pair of extension patterns are arranged not to overlap with the loop-shaped wireless communication coil, andwherein the pair of extension patterns are formed on a surface of the insulative sheet which is different from the front surface of the insulative sheet on which the loop-shaped wireless communication coil is formed.
