Pulse Electronics intros Ferrite sheet antenna for NFCs

SAN DIEGO, USA: Electronic component provider, Pulse Electronics has launched a near field communications (NFC) antenna that enables mobile phones to read data from a distance of up to 40mm.

The antenna sends and receives clear signals when installed in a handset in close proximity to the battery or metal housing. The company’s ferrite sheet antenna can be customized to the varying sizes of handset mechanics. It is easier to implement, and enables safe, non-contact, wireless communication for NFC connectivity to mobile devices.

The planar ferrite sheet-based antenna has dimensions of 35mm x 50mm with a minimum thickness of 0.30mm, including the ferrite/adhesive/antenna flex layers.

The magnetic field strength can be optimized by the type and thickness of the ferrite material and the design of the radiator pattern. The antenna meets EMVco specifications ensuring global interoperability and compatibility of chip-based payment cards and acceptance devices.

“In order to achieve the EMVco target reading distance of 40mm it requires optimization between the mechanics and antenna. Pulse customizes its NFC antennas, matching the circuit values for the device, so tuning is all that is needed to integrate it,” said Maritta Timosaari, sales and marketing director, Pulse Electronics Mobile Division.

Through NFC antennas, mobile devices can communicate with other wireless devices for payments, access and control, credential storage and exchange, and content consumption. Pulse can optimize multi-antenna configurations with an NFC antenna for all-in-one solutions.

In-house testing and measurement is done at Pulse Electronics global facilities. The NFC ferrite sheet antenna is RoHS compliant, comes packaged in trays, and is ready for volume production.
