Disclosed is an antenna module wherein a radiation pattern for near-field communication and a radiation pattern for electronic payment are formed on a flexible printed circuit board and then are coupled to a magnetic sheet, thereby implementing a performance equal to or superior to that of a conventional antenna module through a simplified manufacturing process. The disclosed antenna module comprises a flexible magnetic sheet and an antenna sheet having a radiation pattern and an insertion hole formed thereon. The magnetic sheet has an extension portion formed on one short side thereof, and the extension portion is inserted through the insertion hole and is coupled to the antenna sheet.
