PURPOSE: An NFC loop antenna is provided to adjust a resonant point by adjusting the size of a patch antenna pattern, thereby drastically increasing performance of a two-terminal NFC loop antenna of an NFC communication terminal. CONSTITUTION: An antenna substrate(10) has double sides. A first loop antenna pattern(12) is expanded along with the girth from one inner side of the antenna substrate. A second loop antenna pattern(11) is expanded with the girth from the outside of the first loop antenna pattern. A patch antenna pattern(20) is connected to the first loop antenna pattern on the antenna substrate. The patch antenna pattern has a capacitance component.
