Embodiment Construction
[0024] Such as figure 1 As shown in , the smart card according to the present invention includes an antenna base 10 . The base 10 is made of fiber material. The material is preferably paper. The antenna 12 is silk-screen printed on the base. The antenna consists of four concentric turns. Each end of the antenna 12 forms an antenna contact 14 or 16 . The turns and the antenna contacts are made with polymerizable conductive ink. According to a preferred embodiment, the ink is an epoxy ink doped with conductive elements such as silver, copper or carbon. A cavity 18 is formed in the antenna base by cutting. This cavity is used to accommodate the chip.
[0025] exist Figure 2a with 2b A front view of chip mount 20 is shown in . The base 20 is made of fiber material. According to a preferred embodiment, the fibrous material is paper. Two strips of polymerizable conductive ink 22 and 24 are screen printed on the base 20 . According to a preferred embodiment, the ink is ...
