Note
The EMC filter is used to reduce harmonics of the 13.56 MHz carriers and
perform as an impedance transformer
The matching circuit elements C1 and C2 must be tuned to get the required
matching resistance Rmatch (Xmatch=0) at the I/O pins of NFC IC
The quality factor damping resistors RQ are used to obtain a certain pulse
shape as required by the standard. Normally, RQ is chosen to make the
antenna Q<35

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
