Datasheet

Pulse Electronics introduces an ultra-thin near field communications ferrite sheet antenna. The antenna is 28% thinner than the previous version and still meets the EMVCo specification of 40mm. It enables NFC connectivity to mobile devices for payment sharing, credential storage and exchange, accessing and controlling data, and wirelessly connecting to tags.

Pulse Electronics' NFC antennas are custom-made to fit the mechanical specifications of a variety of mobile devices. The antennas are 35x50x0.133mm in size and operate at a frequency of 13.56 MHz. The contacts are side-by-side in the antenna area for easier implementation and to fit more compactly. The pad size is 2x2mm. The antenna's operation is not affected by close proximity to metal or a battery. The magnetic field strength of the antenna is optimized by ferrite material type and thickness selection and the radiator pattern. The antennas are compatible with several chipsets and can be used for several mobile devices like handsets, phablets, and tablets.

Maritta Timosaari, marketing director, Pulse Electronics Wireless Division, comments: "Reliable antenna solutions are needed for user-friendly and safe contactless commerce. Pulse's new NFC antenna is not only thinner than previous NFC antennas without losing performance, but its side-by-side configuration makes it easier for mobile device manufacturers."

Pulse Electronics' NFC ferrite sheet antennas are RoHS compliant and ready for volume manufacture. The antennas are backed by Pulse's global customer support and in-house NFC testing and measurement capabilities.
