In accordance with one main feature of the invention, on the second side of the module are screen-printed first strip conductors (54) connected through their first ends (55) to the through holes and through their other ends to bond pads of the chip and second strip conductors (56 and 58) connected each respectively on one side to a screen-printed bond pad (57 and 59) and on the other to two of the bond pads of the chip, the bond pads being positioned such that when the module is inserted into the cavity, they are opposite the antenna bond pads and enable the module to be bonded over its entire periphery.
The invention concerns a method for making a set of electronic labels comprising an antenna (12) and a chip (13) assembled together, the set of labels produced including several subsets of p labels of different types in the shape of their antenna, p being not less than two, the set of labels being manufactured in a continuous mode so as to produce the labels in the form of webs of labels. The resulting web of labels thus comprises several subsets of p labels, the labels of a subset being of different types in the shape of their antenna.
The invention concerns a non-contact label designed to ensure traceability of an object comprising essentially a microcircuit (16) and a Y-shaped antenna connected to the microcircuit which contains data required for the traceability of the object, readable from a reader through ultra high frequency (UHF) electromagnetic exchange. The antenna is of the dipole consisting of three main wires, a first main wire (10), a second main wire (12) forming a first dipole with the first main wire and a third main wire (14) forming a second dipole with the first main wire. The angle between the first and second main wires is equal to the angle between the first and third main wires, and the angle between the second main wire and the third main wire ranges between 60° and 180°. Each of the main wires comprises at its end a secondary wire (24, 26 or 28) perpendicular to the main wire.
An RFID-type radiofrequency identification device including a chip (12) and an antenna (10) interconnected on a substrate, wherein said antenna is printed on the substrate, which is attached to an object via an attachment insert means. According to the main feature thereof, the attachment means overlaps at least once at least one coil of said antenna so that the RFID radiofrequency identification device is destroyed if the substrate is separated from the object without removing the attachment means.
A contactless reading system, wherein a chip card is fixed on a planar support of an object such as a book (11) for identification by means of the data contained in the chip card, and a mobile reader (16) provided with an antenna in order to read the data of the card. The antenna of the reader (16) consists of a small-sized convolution disposed in a series with a large-sized convolution, which are concentric and which have the same winding direction. A maximum value is obtained for the component (H) of the electromagnetic field produced by the antenna parallel to the antenna at a given distance from the antenna. Maximum reception by the chip card of electromagnetic signals emitted by the antenna is obtained when the antenna is disposed in a perpendicular position in relation to the support of the card and at the given distance from the card.
