Abstract
A miniaturized dual-loop near field communication antenna of size 15 mm×25 mm is proposed for metal cover smartphone applications. By embedded it with a small rectangular slot of size 8 mm×16 mm loaded metal cover, the direction of the eddy current induced on metal cover will be the same with the current flow the on the dual loop NFC antenna coil. It's worth noting that the proposed NFC antenna design was certified by the Europay, Mastercard and Visa (EMV) test.
