NFC Reader and Tag Antennas

NFC Reader and Tag Antennas

Taoglas have developed a new range of NFC (Near Field Communications) antenna and tag solutions. This year 1.4BN cellphones will ship and up to 40% will have a NFC tag. This means many devices can become a NFC reader to everyone’s cellphone by implementing the technology inside their own device. For this they will require a NFC antenna. Taoglas also has the NFC tags available if required. By implementing NFC you open your device up as mobile payment terminal.

The first off the shelf antenna product in the offering is a standard design, the FXR.01. It operates at 13.56MHz and provides a well matched solution (50ohms) for NFC readers.  The antenna measures approximately 54x37x0.1mm and provides an average NFC tag read distance of 5cm.

This flexible polymer antenna is provided with a coaxial cable connected to the antenna element for ease of connection to the chipset solution. It is also delivered with 3m adhesive and tape for ease of assembly to a plastic (non metal) enclosure by a simple “peel and stick” method.

The FXR.01 NFC antenna has an integrated matching circuit to provide effective antenna matching.  The Q of the antenna/matching circuit combination has been selected to provide a solution where the bandwidth and read performance have been optimized for best tag interrogation performance.

Custom NFC antenna design is also offered by Taoglas where the antenna area is maximized for a specific application in order to enhance interrogation distance. With the NFC protocol being based on magnetic coupling between the reader antenna and the NFC tag antenna, the antenna area will directly relate to interrogation distance. The achievable read distance will vary depending on antenna area. The three main areas for NFC antenna optimization are;

1.      Maximize the area of the antenna design (to fit the device enclosure for example)

2.      Ensure antenna is matched with matching circuit design

3.      Apply ferrite material to improve interrogation distance

Taoglas have also released a passive NFC tag antenna, the FXT.01. It measures 45x34x0.1mm. This is also a peel and stick flexible polymer tag solution. The tag design requires no additional matching components and is ready for direct connection to an NFC chip. Like the FXR.01 the FXT.01 is dimensioned to provide interrogation capability out to 5 cm. distance.  This standard antenna tag is also manufactured in a Taoglas’ flexible polymer material for ease of use and installation. 

With NFC tags being commonly attached to the battery of mobile devices, the NFC tag can be customized with a ferrite layer to provide isolation from the battery or other components in the device the tag is integrated in.
