PURPOSE: An NFC compact antenna is provided to improve a performance by using multiple ferrite substrates and multiple antenna pattern units. CONSTITUTION: An NFC compact antenna comprises an antenna pattern unit which prints a ferrite substrate and a loop pattern. A first ferrite substrate (120) is positioned in a lower part of a first antenna pattern unit. A second antenna pattern unit (130) is positioned in a lower part of the first ferrite substrate. A second ferrite substrate (140) is positioned in a lower part of the second antenna pattern unit. An area of the second ferrite substrate is formed smaller than an area of the second antenna pattern unit.
