【 摘 要 】

In this paper chipless RFID tag, capable of carrying 9-bit data is presented. The tag is optimized for several flexible substrates. With growing information and communication technology, sensor integration with data transmission has gained significant attention. Therefore, the tag with the same dimension is then optimized using paper substrate. For different values of permittivity, the relative humidity is observed. Hence, besides carrying information bits, the tag is capable of monitoring and sensing the humidity. The overall dimension of the tag comprising of 9 ring slot resonators is 7 mm. Due to its optimization on the paper substrate, the tag can be an ideal choice for deploying in various low-cost sensing applications.
