Stackable near-field communications antennas

Abstract:

Techniques regarding one or more NFC antennas that can comprise vertically stacked coils of electrically conductive material are provided. For example, one or more embodiments described herein can comprise an apparatus, which can comprise can a first substrate layer that can comprise a first coil of electrically conductive material that can be wound in a first direction. The apparatus can also comprise a second substrate layer that can comprise a second coil of electrically conductive material that can be wound in a second direction opposite the first direction. The first substrate layer can be stacked onto the second substrate layer. Also, the first coil of electrically conductive material can be operably coupled to the second coil of electrically conductive material through an interconnection via to form an NFC antenna.
