Near field communication antenna

A near field communications (NFC) antenna comprising:

• a multi-layer circuit substrate including a plurality of spaced apart electrically conductive layers each formed from an electrically conductive material;
• a plurality of outer antenna segments electrically connected to one another, each outer antenna segment formed on a respective one of the electrically conductive layers and having a first perimeter or circumference;
• and
• a plurality of inner antenna segments electrically connected to one another, each inner antenna segment formed on a respective one of the electrically conductive layers and having a second perimeter or circumference which is less than the first perimeter or circumference.

A near field communications (NFC) antenna comprising:

• a multi-layer circuit substrate including
• a plurality of spaced apart electrically conductive layers each formed from an electrically conductive material,
• a plurality of spaced apart electrically insulating layers each formed from an electrically insulating material, the electrically insulating layers being interleaved with the electrically conductive layers, and
• a plurality of vias each formed from an electrically conductive material and electrically connecting a respective one of the electrically conductive layers to one or more other electrically conductive layers;
• and
• a plurality of antenna segments, each antenna segment
• formed on a respective one of the electrically conductive layers,
• extending along a perimeter of the circuit substrate, and
• electrically connected to another antenna segment on another one of the electrically conductive layers through a respective one of the vias.
