Microstrip multiple resonator assisted passive RFID tag for object tracking

摘要

Radio Frequency Identification (RFID) tag using microstrip resonator for object tracking is presented in this paper. The passive tag is realized using half wave open circuited Microstrip lines. Effective use of each resonator as 4 bit RFID tag is demonstrated. The resonators are optimized by HFSS and is validated by measurements of the realized prototypes. The tag design is completed with inclusion of an omni-directional antenna as transmitter and receiver along with the resonators. The range of the proposed tag is also measured experimentally in indoor environment.
