Printable RFID antenna with embedded sensor and calibration functions

• An RFID antenna with integrated humidity sensor and calibration functionality for wireless sensor network is proposed. The antenna is composed of series and shunt stubs for impedance matching and reliability for near-field communication. The innovative ladder contour structure plays the key role for humidity sensing, and sensor calibration. The quadrangular end-tip loading is employed to offer capacitance and stability for far-field communication. The prototypes of the antenna are fabricated and tested: antenna effectively senses the ambient humidity levels while demonstrating stable behavior for RFID communication. The antenna has a compact size of 1 × 10cm for 902-928 MHz RFID band.
