Abstract

A new type of antenna with an RH (relative humidity) sensing function using a modified polyimide is proposed for passive RFID sensing. Designed to operate at a frequency that depends on the relative humidity level, the proposed antenna is a passive device that physically and functionally combines an antenna with an RH sensor. The compactness and cost-efficiency of the antenna enables it to realise a passive tag of the RFID sensing without an additional sensor component.
