Printed circuit card includes a circuit identification device comprising a transponder having external antenna flush with surface of insulating plate, where antenna is formed by conductors of the printed circuit

摘要

The printed circuit card has an identification unit with a transponder (4) embedded within the thickness of an insulating plate (1). The transponder has an external antenna (5) flush with a surface of the plate The antenna is formed by at least part of the conductors (30) of the printed circuit. The frequencies of the electromagnetic signals transmitted and/or received by the antenna are different from the operating frequencies of the printed circuit. An independent claim is also included for an apparatus incorporating the printed circuit card.
