Abstract
Described herein are techniques related one or more systems, apparatuses, methods, etc. for integrating a near field communications (NFC) coil antenna in a portable device. For example, the NFC antenna is integrated under a metal chassis of the portable device. The metal chassis and a conductive coating—that is integrated underneath the full metal chassis—are designed to include one or more slots to provide high impedance to Eddy current induced in the conductive coating.
