Introduction
The FXR.08.52.0075X.A.dg is an NFC Ferrite antenna with 75mm twisted pair
28AWG cable and JST connector. It works with specific NFC chips which need to
connect via JST ACH connector.
NFC antennas can be applied in areas not traditionally available to other types of
antennas. A common example is the ability to apply NFC antennas to batteries or
other conductive surfaces. To enable this usage, however, a ferrite flux director
layer is required. This ferrite layer acts to steer the magnetic flux away from the
metal or other conductor, where it would otherwise result in loss or complete failure
to communicate. Taoglas NFC antennas can therefore be customized with flux
director layers to enable this flexibility in usage. The coil inductance noted below
can help estimate a capacitance value for creating resonance at 13.56MHz.

Antenna Application
3.1. Test setup
A test fixture is used to measure the maximum interrogation distance. The
FXR.08.52.0075X.A.dg antenna is connected to a NFC evaluation board and then
placed on the fixed part of the fixture.

The test sample is placed on a thin sheet of plastic connected to the movable part of
the fixture. Then the distance is carefully adjusted until the reader can no longer read
the sample, thus the maximum interrogation distance is displayed in the ruler.

3.2. RFID tags used for test
A total of 8 RFID tags were used to measure the interrogation distances. The next
picture shows type 1 and type 2 tags, respectively.
Type 1
Type 2
Type 1 tag is based on ISO/IEC 14443A standard and has 512 bytes of memory.
Type 2 tag is based on ISO/IEC 14443A standard and has 192 bytes of memory.
The next picture shows the Tag-it HF-I RFID tags from Texas Instruments: RI-102-
112, RI-I11-112, RI-I03-112, RI-I16-112, button type, and RI-I17-112.
The Tag-it HF-I Plus Transponder Inlay family of Texas Instruments RFID is based on
the ISO/IEC 15693 standard for contactless integrated circuit cards (vicinity cards)
and ISO/IEC 18000-3 standard for item management.
