Planar Spiral Inductors Parameter Extraction needed to design a Wireless Power Supply System

The wireless power systems of millimetre dimensions are nowadays used for a wide range of high technology applications. In this paper we aim to extract the planar spiral inductors parameters to optimal design them for the design of a wireless power supply system used to supply the peacemaker or other similar devices. The planar spiral inductors are analysed first to extract their specific parameter. Then the influence of the ferrite on the spiral inductors parameters is analysed to improve the inductor performances by increase its inductance. Next using the optimized inductor, a wireless power supply system is designed and 3D numerical modelled to also extract its parameters. Different distances between emitter and receiver inductors are considered trying to estimate the real possible distance that can exist between them if they will form the wireless power supply of a peacemaker. Finally, we analyse the influence of ferrite, considering different thicknesses, also on the wireless system's parameters, aiming to increase them for improvement of device performances.
