Electronic device including coil

This invention describes a portable device, like a smartphone, that combines several wireless features into a single compact design. It achieves this by embedding coils for near-field communication (NFC), wireless charging, and magnetic secure transmission (MST) directly into a flexible circuit board. This circuit board is cleverly tucked between the device's battery and its back cover, with each coil's wiring spread across different layers of the board to save space.

Why it matters: While MST technology, a core component of this invention, has largely been phased out of new devices since 2020, the underlying challenge of compact multi-coil integration for NFC and wireless charging remains relevant.
