The Near Field Communication Interface and Protocol (NFC), is a secure and wireless way to exchange communicate between various devices that are in close proximity to one another. The NFC antenna are the sending and receiving elements of a wireless data interchange system which uses an electromagnetic field as its media.
Today’s NFC market is growing rapidly worldwide, and currently the most popular NFC Applications are Cashless Transactions. However, there are several other uses that are also being rapidly adopted such as, physical access, driver identification, keyless entry systems, peer-to-peer file sharing, and credential storage and exchange. The uses are endless.
In line with the global growth trends of the NFC market, Premo Group has developed different ferrite-based antenna concepts that have been specially designed for those NFC applications where component size and performance is critical.
Typically, NFC antennas are found in a normal loop track,(loop embedded in a PCB). But sometimes there is not enough space or volume to provide the loop in a PCB and include other sensors in the devices. For these space constrained configurations, it is possible to use Premo ferrite coils for NFC instead of air loop antennas.
In this case, Premo can provide almost the same shape as the antennas used for low frequency (125 or 134 kHz), but with a different ferrite material.
The ferrite material is optimized to work in the 13.56 MHz range, different from the other material used in low-frequency applications, but with the same shape and size.
