Abstract: Method for the manufacture of a chip card module in which a polymer material including conductive particles is deposited in two connection wells or on two conductive pads formed in a conductive sheet positioned on the back face of the module. This polymer material forms, after deposition, an excess thickness on the back face which comes, during the insetting of the module, into contact with the ends of an antenna. Between the manufacture of the modules and their insetting, the modules are positioned on a strip which can be rolled up on itself for the purpose of its storage.

Abstract: Electrical circuit for a smart card chip module, including an insulating layer having a front main face and a rear main face. An antenna is made in a first conductive layer laying on the rear main face. This antenna extends over an antenna area delimited by a peripheral edge. The antenna includes at least one inner loop and one outer loop. The outer loop runs along the peripheral edge except over at least one first connecting segment diverted from the peripheral edge, towards or in a central zone of the antenna area. Further, the outer loop of the antenna includes at least a second connecting segment diverted from the peripheral edge towards a central zone of the antenna area.

Abstract: The present invention relates to card-type information substrates, such as payment cards, in which a frame is implemented so as to impart increased weight and/or superior appearance to the card-type substrates, wherein the influence of the frame on the RF performance of the card-type substrate is taken into consideration. For example, in illustrative embodiments the influence of a conductive material in the frame is reduced by selecting one or more appropriate features countering the negative effect on the RF performance.

Abstract: The invention relates to a chip card designed to communicate data in a contactless mode with a card reader operating at a reading frequency. The resonance frequency of the chip card may change according to the capacitance of the chip used in the contactless mode of the chip card. In order to be able to use various chips without changing the booster antenna design, the card antenna circuit is provided with a capacitance element such that the chip card including the card antenna circuit and the chip module has two different resonance frequencies, one of which being equal to, or lower than, the reading frequency and the other being equal to, or greater, than the reading frequency. This create a broadband wherein the reading frequency falls.
