Planar Antenna Captures NFC Data

Oct. 8, 2012
A near-field communications (NFC) antenna enables mobile telephones to read data from a source at distances to 40 mm. Theantenna sends and receives clear signals even when installed in close proximity to a battery or metal housing.

A near-field communications (NFC) antenna enables mobile telephones to read data from a source at distances to 40 mm. Theantenna sends and receives clear signals even when installed in close proximity to a battery or metal housing. The ferrite sheet antenna can be customized to different sized handset designs and enables safe, noncontact, wireless communications for mobile devices. The planar ferrite sheet-based antenna measures 35 x 50 mm with 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 NFC ferrite sheet antenna is RoHS compliant, comes packaged in trays, and is ready for volume production. It is available in a variety of sizes and can be custom configured to a customer’s specifications.
