Abstract
A smartcard (10) is formed in part by a laminate layer (77). The laminate layer (77) is made up of a plurality of dielectric layers (11,30), insulating layers (45, 50), resistive layers (55), and electrically active structures. The electrically active structures include a capacitive structure (23) which is formed from one of the dielectric layers (11) and an antennae (32) which is made from a conductive layer that is formed into a spiral pattern on the another dielectric layer (30). These layers (11,30, 45, 50, 55) are formed separately and then pressed together to form the laminate layer (77).
