Electronica: Murata shows 'smallest' HF-band RFID tag
Murata has introduced its smallest HF-band RFID tags.
Operating in the 13.56MHz band also used by contactless IC cards, the LXMS33HCNG-134 tag measures 3.2 x 3.2 x 0.7 mm.
Compliant with ISO 15693 standard, the tag can be used with any reader/writer that conforms to the same standard.
The tag is suitable for use in most operating environments including high temperature and high humidity so it suits a wide range of appliance and object tracking, certification and authentication applications.
Normally, an RFID device requires an antenna and the IC tag and due to the frequencies involved the antenna tends to become extremely large.
However, by applying multi-layer circuit board and high-frequency module techniques, Murata has been able to incorporate the antenna within the ceramic substrate.
This approach makes the tag more resistant to environmental conditions.
