CDI and Pulse Electronics introduce 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.
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. 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 your specifications. CDI / Pulse can optimize multi-antenna configurations with an NFC antenna for all-in-one solutions.
