Abstract
The disclosure illustrates a NFC antenna. The NFC antenna includes a first radiating portion and a second radiating portion. The first radiating portion is formed by a first conducting wire surrounding an axis core. The second radiating portion is formed by a second conducting wire surrounding the same axis core based on a surrounding direction which the first radiating portion surrounds the axis core. A second signal input terminal of the second radiating portion is electrically connected to a first signal input terminal of the first radiating portion. An open end of the second radiating portion is disposed proximately to a first signal output terminal. Thus, the NFC antenna can reduce the interferences affected from surrounding metal elements, and improve a quality factor of the NFC antenna.
