Abstract:
Removable card for a contactless communication contains an antenna (4) formed of threads (10) placed on the external surface of the body (1) of the card and covered by a layer (7) of a ferromagnetic material. In advantageous adjustment the antenna (4) contains on one area (2) of the card eight threads (10) and both areas (2) of the card are covered by a layer (7) of a ferritic foil. The antenna (4) is connected to the series with element (12) with capacity and the resistance (11) on the other side. Resonant circuit is tuned in for the final frequency from 13.0 to 15.0 MHz. The signal from the antenna (4) is read between the first and the second thread (10) from the side of the element (12) with capacity. The production method for the antenna on the body of the removable card resides in the fact that a groove of the conductive path (5) shape is dredged on the surface of the card's body (1), the groove is filled with a conductive material and a ferromagnetic material layer (7) is applied on the surface of the area (2) covering the antenna (4).
