Systems and methods for providing resonant wireless charging 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, GPS, and cellular drives respectively, while a wireless charging antenna sharing the same mechanical connections provides a differential drive across the antenna ends, forming a primary wireless charging coil. In an embodiment, a smaller multi-turn coil is connected to the primary wireless charging coil, and may overlay a device speaker and may also be shielded by a ferrite material. This structure or a dedicated similar structure on the device is then used for resonance-based wireless charging of the device.
