The transparent NFC antenna improves the radiation efficiency of standard NFC antennas by including a transparent conducting film such as metal mesh in the transparent portion, and metalized film in the non-transparent portion. The metalized film can extend along a narrow width of the perimeter of the transparent portion. In one implementation, the transparent NFC antenna can be incorporated into a touch-enabled display panel of a wrist-wearable device without interfering with the usability or viewability of the touch-enabled display panel. Various other implementations are also disclosed.

Various other devices, systems, and methods are also disclosed.

Abstract: The disclosed apparatus may include an antenna radiating structure that includes an active transparent mesh portion as well as a non-transparent antenna radiator portion. By combining transparent metal mesh and non-transparent metallic film into the antenna radiating structure, the disclosed apparatus results in improved radiation efficiency. Moreover, when overlaid on a transparent lens (such as with a pair of augmented reality glasses), the antenna radiating structure leaves the optical transparency of the lens largely unaffected due to the placement of the non-transparent metallic film. Various other implementations are also disclosed.
