Sheet Antenna

December 1, 2012

Pulse Electronics Corp. (San Diego, CA) has introduced a near-field communications (NFC) antenna that enables mobile phones to read data from a distance of up to 40 mm. The ferrite sheet antenna sends and receives clear signals even when installed in a handset in close proximity to the battery or metal housing. It measures 35 x 50 mm with a minimum thickness of 0.30 mm, 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 for global interoperability and compatibility of chip-based payment cards and acceptance devices. The antenna is RoHS-compliant and comes packaged in trays in a variety of sizes.
