    摘要: A coupling device is formed by a continuous conductive path having a central section and two extremity sections, the central section forming at least a small spiral for inductive coupling with the transponder device, the extremities sections forming each one large spiral for inductive coupling with the reader device, wherein the small spiral shows a larger pitch than the ones of the large spirals, and wherein the two extremities of the continuous path are loose such that the coupling device forms an open circuit. The pitches of the large spirals are chosen such as that the interturn stray capacitances is important and that the large spirals have mainly a capacitive behavior. And the pitch of the small spiral is chosen such as that the interturn stray capacitances are negligible, and that the small spiral has mainly an inductive behavior.

    摘要: The invention concerns the production of contactless transmission chip card, and particularly mixed cards operating with or without contact. The method for the reliable and efficient setting of an integrated circuit module (M) and of an inductive transmission antenna (A), consists in producing the module providing connection ranges for the antenna, making an antenna with a flat coiled wire, and soldering the ends of said antenna on the module ranges, then making a plastic wafer (30) provided with an opening, the bottom of this opening being closed by an adhesive film (34). The module and the antenna are set against the wafer, and maintained by the adhesive material at the bottom of the housing. Another wafer (40) is directly mounted on the assembly.
