MICROELECTRONIC MODULE WITH A DOUBLE COMMUNICATION INTERFACE, IN PARTICULAR FOR A CHIP CARD.

摘要

The invention relates to a microelectronic module (7) with a dual contact and non-contact communication interface, in particular for a smart card, comprising on the one hand a substrate (13) provided with a terminal block formed by a set of electrical contacts ( 10) connected to a contact communication interface of a first electronic chip (21) and further comprising a main antenna (8) composed of at least one turn and whose terminals are connected to the communication interface without contact of a second electronic chip (22) .This microelectronic module is characterized in that it further comprises a resonant circuit (9) capable of channeling the electromagnetic flux received by the resonant circuit (9) towards the antenna main (8) of the module.L'invention is particularly applicable to the reliable and economical realization of smart card dual contact communication interface and contactless.
