Applications
Features and Benefits
Airline Ticketing Systems Payment Processing Systems Apparel Tagging Readers
Near Field Communication (NFC) Antennas optimize
detection performance for both Ferrite and non-Ferrite
based applications
Plated Pads
Provide electrical contact to
connecting spring clips or
pogo pins mounted on the
application PCB
Selection of antenna
sizes:(15 by 25),
(23 by 27), (34 by 46)
and (45 by 55)
Offer increased design
flexibility to the application
developer
Flexi material
Facilitates easy integration
on the application substrate
due to its pliability
Ferrite* layer
Eliminates interference effects
from metallic or conductive
surfaces when antenna is applied
on these (Remark: Non-Ferrite
version antennas are used on
non-metallic or non-conductive
surfaces)
Double-sided adhesive tape
with liner(not shown, on
underside of antenna)
Enables easy peel-and-stick
mounting on the application
substrate
