Mutual inductance of two adjacent coils, is one of the critical operating principles in near-field wireless power and data transmission systems, significantly impacting their performance. Hence, in this study, the mutual inductance between two similar concentric planar spiral coils is investigated. The effect of main parameters, including the track width, w, and the space between two consecutive turns, s, with a fixed inner and outer diameter of the coils are investigated. The Taguchi method using the L16 array in Minitab environment is used to optimize design parameters. The samples of applied Taguchi, are modeled and simulated via ANSYS Maxwell. The results show that the mutual inductance increases by reducing the two investigated parameters. Based on the Taguchi analysis, it is revealed that the effect of the response for both of the investigated parameters is very close. By applying the main effect analysis the obtained results are verified. This interesting result is important in the design of planar spiral coils while we have fabrication limitations in a real sensor design realization. }, keywords = {Mutual Inductance,Planar Coil,3D Modeling}, url = {https://jaree.scu.ac.ir/article_17916.html}, eprint = {https://jaree.scu.ac.ir/article_17916_204650971dda5cc18ccb6da366cb2945.pdf} }
