Several conditions apply when matching:
• Environment of the design.
• Placement of Antenna
o The antenna should be placed as close to the matching network as possible
o How close the NFC antenna is placed to other metalwork and other coils within the design.
• Antenna design
o Optimization of the matching network is likely to be needed and this should be done with the antenna in the
desired position.
• NFC normally operates from 1 to 4cm between devices. Final optimization of the matching circuit should be com
pleted to ensure compliance.
• Designers need to consider interoperability with other devices. The antenna and matching network contribute to best
interoperability.
CONNECTION TO THE PCB
While soldering thin wires to the pads on the antenna is possible, great care must be taken, (see manual soldering Sec-
tion 10.1). However it is recommended to make contact to the antenna pads via Pogo Pins. These are soldered onto the
product PCB, and interface mechanically via a pressure contact to the pads on the NFC antenna. Volume applications
using the NFC antenna should always use Pogo Pins to make the connections.
