MATCHING NETWORKS
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.
ANTENNA RESPONSE – RETURN LOSS
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.
