Abstract

The research proposes a semi-octagonal shaped passive chipless RFID moisture sensing tag. The tag is capable not only for traceability, but also, to sense the moisture in surroundings, hence referred as a humidity sensor chipless RFID tag. The tag has been designed and its performance has been analyzed for various substrates such as, Taconic TLX-0, FR4, Kapton HN®, Rogers RT/Duroid 5870 and Rogers RT/Duroid 5880. Moreover, Rogers RT/Duroid 5870 is used to evaluate the tag’s ability to sense and measure the humidity and moisture levels. To acquire sensing behavior, Kapton tape is deployed on largest slot of the tag. As the humidity level varies, there is a change in the electrical properties of Kapton, which in return outputs sensing behavior of the proposed tag. The proposed tag is ideally capable to tag 210 number of unique objects while maintaining compact dimensions of 13 mm × 7 mm. The tag proclaims an astounding sensing behavior towards varying atmospheric humidity levels. The repositioning of frequency notches is evaluated as moisture sensing. The tag anticipates a steppingstone for humidity sensing, to be deployed in agriculture industry.
