tablets, laptops, printers and other unique system using
NFC technology. It is intended for pairing and sharing
modes typically found in non-payment NFC applications.
The W7013 has a semi-flexible sintered ferrite backing
designed to optimize magnetic fields, thus increasing the
corresponding field strength of the antenna. The W7013
is a thin, flexible antenna which can be fed with customer-
supplied interconnect cables by using direct-solder meth-
ods or with the use of Pulse’s own interface connections.
Mounting the antenna is easily accomplished using the thin
but aggressive holding adhesive backing. Recommended
for mounting on the inside of battery covers, directly onto
PCB or metal surfaces, or locations where the antenna will
be on or in close proximity to ground planes or displays.
