An antenna system is described for implementation in devices enclosed in a metallic enclosure, where a small opening is introduced in the metallic enclosure and a magnetic field is generated external to the metallic enclosure for use in near field communication applications. An antenna structure is described that is internal to the metallic enclosure that generates a magnetic field on the axis of the opening in the metallic enclosure.

NFC antenna system for metalized devices

A multi-feed antenna in provided, including multiple feed elements associated with multiple frequency regions, respectively, and a folded loop element for radiating energy. Each of the multiple feed elements is capacitively coupled to the folded loop element.
