Abstract
A near field communication (NFC) antenna apparatus with improved operation range, and a portable device having the same are provided. The NFC antenna apparatus includes a first NFC antenna proximate a front surface of the portable device, such as within a black mark area of a front side. A second NFC antenna is proximate a rear surface of the device, such as between a rear case and a PCB. In an exemplary embodiment, the second NFC antenna comprises an outer edge loop, and an inner loop to bolster magnetic field strength in a weak radio area generated by the outer edge loop.
