Abstract:

We used electromagnetic simulation software FEKO which is based on the method of moments （MOM） to establish 3D modeling planar spiral coil and obtained the resonant frequency of the planar spiral coil by calculating 50 cm nearfield values. This method omitted the traditional complex mathematical calculations on planar spiral coil selfinductance. We manufactured the planar coil according to the simulation size, and tested the S₁₁parameter. The comparison of experimental and simulation results proved the accuracy of the simulation. This approach greatly simplified the design of the planar spiral coil. Finally, we used a coil the resonant frequency of which is 19.3 MHz to light up a led array that proved the feasibility of the design for wireless energy transmission system.

Key words: magnetically coupled resonance, wireless power transmission, planar spiral coil
