First Claim
Patent Images
1. A portable device comprising:
- one or more processors;
a memory configured to the processors;
a spiral shaped near field communications (NFC) coil antenna configured to the processors wherein the spiral shaped NFC coil antenna is configured to include an first loop, a second layer loop that is tied to the first loop, and an third loop that is tied to the second layer loop, wherein the first loop, the second loop, and the third loop are gradually distributed to cover loop areas based on listeners with different sized antennas, and wherein the different sized antennas have progressively larger sized antenna loop areas.
