NFC Reader and Tag Antennas

NFC Reader and Tag Antennas

Taoglas have developed a new range of NFC (Near Field Communications) antenna solutions. This year 1.4BN cellphones will ship and up to 40% will have a NFC antenna. This means any device implementing one of our NFC solutions can communicate to a cellphone using NFC. For this they will require a NFC antenna. 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. The antenna measures approximately 54x37x0.1mm and provides an average NFC 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.

The FXR.05.A and FXR.07.A are circular flexible NFC (Near Field Communications) tag antennas for use in mobile devices and other applications. This design is matched for optimal performance with typical NFC chipsets. The design provides a flexible NFC antenna that can be adhered to the plastic enclosure of the device for ease of installation.

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
