This paper proposes a chipless radiofrequency identification system (RFID) that is insensitive to the rotation direction. In order to make the tag orientation insensitive, this research first explores the field pattern of the resonator and compares it with the short dipole antenna, and we select the most suitable resonator to make the tag. The dual-antenna mechanism is used to read the total power, and we use HFSS full-wave simulation to simulate analog random sampling 30 tags with different IDs. Then implemented and measured the tags, at last analyzed the reading reliability of the tags.
When the tag is placed on the front plane and rotated along the y-axis, x-axis, and mixed xy-axis, the reading correct rate of the single-antenna mechanism proposed in the literature is 94.29%, 54.76%, and 39.46%, respectively. The reading correct rate of the dual-antenna mechanism in the study is 94.92%, 88.41%, and 80.95%, respectively.
Finally, the reading reliability of the tag is analyzed and it is found that it is compared with the previous research, the readability rate is greatly improved, so this paper demonstrates the feasibility of chipless RFID under different placement angles.
