NFC ferrite sheet antenna meets EMVCo 40 mm specification

The ferrite sheet antenna enables mobile devices to read data from a distance of up to 40 mm to enable them to communicate with other wireless devices for payments, access and control. EMVCo specifications ensure global interoperability and compatibility of chip-based payment cards and acceptance 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 x 50 mm in size with a minimum thickness of 0.185 mm and a pad size of 2 x 2 mm.

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 40 mm 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. The company 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.
