These two situations lead to the risk of electronic document failure
Specifically, when the separated part of the wire is located in the cavity, it can come into contact with conductive parts (such as current feeds) located on the inner surface of the module, leading to a non-negligible risk of short circuits
Likewise, when a misplaced portion of the wire is located on the contact area between the end of the antenna and the connection terminal to the microprocessor, this results in additional thickness and reduced contact area

Embodiment Construction
[0026] figure 1 The illustrated microcircuit card 10 comprises a body 12 of plastic material defined between a front surface 12a and a rear surface 12b extending substantially in a horizontal plane. The body 12 is a thin plate of plastic material. Card dimensions are specified in the ISO 7810 and ISO 7816 standards, and they have the following values: 85 millimeters (mm) x 54 mm x 0.76 mm. Its vertical thickness is negligible compared to the width and length dimensions of the card.
[0027] Such a body 12 is made by any method. The conventional method is to laminate layers of plastic material by hot rolling. The layers have various functions. Thus, the central inner layer or substrate may be a structural layer that imparts its rigidity to the body 12 of the card 10 or serves as a support for electronic components. The intermediate layer on either side of the substrate may include inscriptions or decorations that have an informative or decorative function. The outer layer...

An electronic document, an antenna support and a method for manufacturing the electronic document. The invention relates to an electronic document comprising: a body (12) comprising a cavity (24) open on one surface of the body (12) and defined by walls, the body (12) also comprising an antenna (36) comprising at least one turn (36c) extending between two ends (36a, 36b) leading to a wall of the cavity (24); a module (14) comprising ) comprising a microprocessor (16) and at least two connection terminals (20a, 20b) for the antenna (36) and electrically connected to the microprocessor ( 16) and is electrically connected to the ends (36a, 36b) of the antenna (36). The ends (36a, 36b) of the antenna are arranged in a zigzag pattern and consist of at least two straight parts (42) connected to each other by a bend (44), the straight parts (42) leading to the cavity opposite to which they terminate. The walls are angled.
Description
technical field [0001] The invention relates to electronic documents (documents électroniques), such as integrated circuit (IC) cards or identity documents. [0002] More specifically, the present invention relates to an electronic document comprising a body having a cavity opening into one of the faces of the body and defined by walls, the body further comprising an antenna having a at least one turn extending between the two ends in the cavity; a module comprising a microprocessor and at least two connection terminals dedicated to the antenna and via electrical connection means Electrically connected first to the microprocessor and second to the end of the antenna. Background technique [0003] Electronic documents such as microcircuit cards comprising an antenna for remote communication with a terminal are known in the prior art. Such electronic documents comprise antenna supports commonly referred to as “inlays” and traditionally produced using ultrasonic methods as de...
