Systems and methods for providing NFC (near field communications) in a portable communications device utilize antenna arms formed from openings in a metal unibody construction. Two of the antenna arms are driven by WiFi and cellular drives respectively, while an NFC antenna drive sharing the same mechanical connections provides a differential drive across the antenna ends, forming a primary NFC coil. In an embodiment, a smaller multi-turn coil is connected to the primary NFC coil, and may overlay a device speaker and may also be shielded by a ferrite material.
