Abstract
Disclosed are a NFC antenna module which maximizes antenna performance by mounting a radiation sheet in such a manner as to overlap a part of an antenna sheet and a portable terminal comprising the same. The disclosed NFC antenna module comprises: a first antenna sheet having a first radiation pattern formed along the outer periphery of a first central portion; a second antenna sheet having a second radiation pattern formed along the outer periphery of a second central portion in such a manner as to partially overlap with the first radiation pattern; and an electromagnetic wave shielding sheet laminated on the first antenna sheet and the second antenna sheet.
