So NFC is just a method of communication between two devices at short distance. What makes the NFC antenna design simple or easy?
If you know much about antennas, the first question you might ask is what is the
operating frequency of NFC. It turns out that these devices operate around 13.56 MHz. The corresponding wavelength is 22 meters long -
this means to get a nice half-wave dipole antenna (that radiates well) we would need a device about 11 meters in length.
