The Tag-it HF-I RFID tags from Texas Instruments tags used for measurement are as following: RI-
102-112, RI-I03-112 and Button. The below pictures show the different tags.
FIGURE 6.1.3 THE DIFFERENT RFID TAGS USED FOR MEASUREMENT
Texas Instruments Tag-it HF-I standard transponder inlays consist of 13.56-MHz high- frequency
(HF) transponders that are compliant with the ISO/IEC 15693 and ISO/IEC 18000-3 global open
standard. The Tag-it HF-I standard transponder inlays available in various inlay shapes also form
the basis of consumable smart labels for use in markets requiring quick and accurate identification
of items. The passive (no battery) transponder inlays are thin and flexible, offer a general purpose
read/write capability, and are designed to be easily converted into paper or plastic labels.
The five sizes rectangular standard NFC antennas are under the detection distance test in free
space. The below figures show the detection distance between NFC antennas and the three RFID
tags.
