Abstract
A smartcard having a metal layer having an RF antenna arranged in or opposite a recess region, a module having an RF chip, and a conductive-material pattern that is arranged in or opposite the recess region and includes a central region and at least two conductive-material traces that are separated and remote from one another, in order to allow a magnetic field to pass through said antenna, and configured so as not to form a closed loop, said conductive-material pattern being configured to form a capacitance that is electrically connected to the antenna, the value of which is determined so that the capacitance formed by said pattern, which is associated with the capacitance of said antenna, allows the resonant circuit formed by the antenna and said pattern to resonate at a determined communication frequency.
