Abstract(in English) | A novel measurement of the resonance frequency for contactess IC cards is presented. The resonance frequency of the contactless IC card was difficult to precisely determined because of electro-magnetic coupling between the antenna in the card and measurement probes, although the frequency is very important factor on energy and data transmission. Thus, an electro-optic-sampling (EOS) probe was employed to detect the resonance frequency of the cards. By using the EOS probe, precise resonance frequency measurement is achieved without influence of electric coupling. |
