摘要：

Great notice is taken of electromagnetic TD (IDentity) transmission systems. Therefore, the 3-D numerical analysis is useful for optimum design of high frequency ID card systems which have complex structure. In this paper, we propose a new method for computing the transmission performance employing the 3-D finite element method. In this method, the current vector analysis and the magnetic field analysis are coupled. The effectiveness of this method is clarified through the comparison with the measured results of the induced voltage of the secondary coil. In addition the influence of the angle formed by the primary and the secondary coils on the directivity is investigated.
