Study of Inductance-Coupling-RFID Tag's Quality Factor

Abstract:

To improve the read performance of RFID tags,improve the quality factor is very important. Firstly,from theory and practical, confirmed that quality factor Q is very important for RFID tags,a higher Q means the tag could have a good performance. Then,through calculations and simulation,analysis the influence factors of Q. With simulation figures show that length, width, space, thickness of the tags coil all affect the Q,but when manufacturing of tags , the control of manufacturing quality and accuracy is very difficultly. Finally, shows many figures about tags manufacturing quality and accuracy of manufacturing which have lower Q and badly read performance.
