The W3580 is a flexible Near Field Communication (NFC)

antenna ideal for tight-space embedded products such as

tablets, laptops, and payment terminal devices. It is intend-

ed for secure payment applications where connect distanc-

es are highly constricted to keep sensitive information safe.

The W3580 has a semi-flexible sintered ferrite backing

designed to optimize magnetic fields, thus increasing the

corresponding field strength of the antenna. Mounting the

antenna is easily accomplished using the thin but aggressive

holding adhesive backing. Recommended for mounting on

the inside of battery covers, 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

- Excellent for tap-n-pay applications

- Well-known antenna concept, reliable technology

- RoHS Compliant Product

Applications

- Mobile devices

- Payment terminals

- Sharing / pairing

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