Finite Element Analysis of Contactless Power Transmission System Using Meander Line Antennas

摘要

This paper presents finite element analysis and optimization of contactless power transmission systems composed of a pair of meander line antennas. In the electromagnetic field analysis, the circuit equations are coupled with the Maxwell equations. The shape optimization of the meander line antennas is performed using micro genetic algorithm (μGA). The optimized antennas are shown to have the resonant frequency identical with the driving frequency. Moreover, the higher power transmission rate increases with the number of folding of the antennas.
