KONTAKTLOSES ELEKTRONISCHES MODUL FÜR KARTE ODER ETIKETTE

摘要

The electronic module (6) has a support substrate for a microcircuit (7) which is connected to an antenna (2) to allow non-contact communication between the card and an external device. - The antenna is contained entirely in the electronic module, and has its winding formed in the plane of the supporting substrate. The antenna is in the shape of a circular or square spiral approximately 12 mm across, with its terminals connected to the contact pads of the microcircuit. The antenna has between six and fifty turns, each of width between 50 and 300 micron, and separated by a distance of between 50 and 200 micron.
