Why use a Ferrite Shielded NFC antenna Vs a regular flex PCB NFC antenna?
•When a metal-content object (i.e. battery, plate, GND PCB, LCD display) is placed near, above
underneath the NFC antenna, the magnetic field will generate undesired EM current on metal plate,
which are called eddy currents which will not permit communication unless customization is done
•These eddy currents will absorb power, weaken the E-field and lead to detuning of the antenna,
rendering it non-operational
• Most of the time it is necessary to "load" or "shield" the antenna with ferrite or other mechanically
precise metals for proper operation in metallic environments/layouts
