摘要:A contactless reading system, wherein a chip card is fixed on a planar support ofan object such as a book () for identification by means of the data contained in the chipcard, and a mobile reader () provided with an antenna in order to read the data of the
card. The antenna of the reader () consists of a small-sized convolution disposed in aseries with a large-sized convolution, which are concentric and which have the samewinding direction. A maximum value is obtained for the component (H) of theelectromagnetic field produced by the antenna parallel to the antenna at a givendistance from the antenna. Maximum reception by the chip card of electromagneticsignals emitted by the antenna is obtained when the antenna is disposed in a
perpendicular position in relation to the support of the card and at the given distancefrom the card.
