_Pulse Part Number W3579_
The W3579 is a flexible Near Field Communication (NFC) antenna ideal for tight-space embedded products such as tablets, laptops, and payment terminal devices. It is intended for secure payment or security access applications where connect distances are constricted to keep sensitive information safe.
The W3579 has a semi-flexible sintered ferrite backing designed to optimize magnetic fields, thus increasing the corresponding field strength of the antenna. The W3759 is a thin, flexible antenna that can be fed with customer-supplied spring clips, contacts, direct-solder methods or with the use of Pulse’s own W9908/W9909 C-clips. 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.
