Electrical Specifications

The W7013 is a flexible Near Field Communication (NFC)

antenna ideal for tight-space embedded products such as

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.

Features

- Excellent performances on metal surfaces

- Thin, semi-flexible structure

- Easily assembles to device covers or mechanics

- Well-known antenna concept, reliable technology

- RoHS compliant product

Applications

- Mobile devices

- Reader / Writer devices

- Sharing / pairing

NOTE: Electrical characteristics depend on distance from metal objects and the location of the antenna on the device.
