Abstract: A mobile device includes an NFC (Near Field Communication) antenna including a metal coil and a first dielectric substrate, a coupling metal element, and a second dielectric substrate. The metal coil is disposed on the first dielectric substrate. The coupling metal element is adjacent to the metal coil. The coupling metal element does not directly touch the metal coil. The coupling metal element is disposed on the second dielectric substrate. The coupling metal element is configured to adjust the operational frequency of the NFC antenna.
