Pulse Electronics Introduces Ultra-thin NFC Ferrite Sheet Antenna

Pulse Electronics

40% thinner while meets EMVCo 40mm specification

Pulse Electronics Corporation introduces a near field communications (NFC) antenna that is 40% thinner than similar NFC ferrite sheet antennas, while still complying with the EMVCo specification. The new ferrite sheet antenna enables mobile devices to read data from a distance of up to 40mm to enable them to communicate with other wireless devices for payments, access and control, credential storage and exchange, and content consumption. EMVCo specifications ensure global interoperability and compatibility of chip-based payment cards and acceptance devices.

“Reliable antenna solutions are needed for user-friendly and safe contactless commerce, as data from IHS iSuppli predicts shipments of NFC antenna-equipped devices to reach 580 million units by 2015,” said Maritta Timosaari, sales & marketing director, Pulse Electronics Mobile Division. “Pulse’s new NFC antennas are not only thinner, but they have excellent signal integrity, can be customized to the varying sizes of handset mechanics, are easy to implement, and enable safe, non-contact, wireless communication for NFC connectivity to mobile devices.”

Pulse’s thinner NFC antenna sends and receives clear signals even when installed in a handset in close proximity to the battery or metal housing. It is 35 × 50mm in size with a minimum thickness of 0.185mm and a pad size of 2 × 2mm. The antenna is constructed of a thin ferrite with one-sided flex and a thinner adhesive. The contacts are in the antenna for easy implementation and a smaller area. To achieve the EMVCo target reading distance of 40mm the mechanics are optimized with the antenna. Pulse customizes its NFC antennas, matching the circuit values for the device, so tuning is all that is needed to integrate it into the mobile device.

The NFC ferrite sheet antennas are RoHS compliant, come packaged in trays, and are ready for volume production. They are available in a variety of sizes and can be configured to a customer’s specifications. Pulse can optimize multi-antenna configurations with an NFC antenna for all-in-one solutions. In-house testing and measurement are done at Pulse Electronics’ global facilities to ensure that the antenna will perform optimally throughout its life cycle.
