Abstract (en)

[origin: US6522308B1] The invention thus concerns a coupling antenna connected to an electromagnetic wave transceiver device containing one or several integrated capacitors. This coupling antenna includes at least one screen printed turn (24) on a support (28) consisting of an insulating dielectric support and also includes a screen printed capacitor on the support, connected in parallel, thereby reducing the capacitance supplied by the capacitor(s) built into the device, so that the resulting capacitance forms a resonating circuit with the turn. The invention also concerns the fabrication process of such an antenna and the use of this antenna in a contactless or hybrid contact-contactless smart card.
