摘要： A method for phase modulation of a carrier signal from a transmitter to a contactless transponder in which data is coded as consecutive symbols, each corresponding to a predefined number of carrier cycles, and in which a symbol time is at least two cycles of the carrier signal includes, at the transmitter, spreading a phase jump of a symbol in relation to a preceding symbol over a first part of the symbol time. The establishment of the phase jump is completed in the first part of the symbol time. The periods of the cycles are constant during a second part of the symbol time.

摘要： This method of identification between an interrogation system (1) such as an arch and labels (E) placed on objects to be identified and called upon to pass through the interrogation field (2) functions by the sending of control signals from the interrogator (1) to the labels (E) so that the latter transmit their codes. The known interrogation mode in which the codes are supplied bit by bit and the labels responding simultaneously are inhibited in turn so that only one is active and identified at any one time, is preceded by an identification test during which all the labels send their code at one go all at the same time, which allows immediate identification if only one label is present. When a label has been identified, the interrogator (1) isolates it in order to exchange particular information with it.

摘要： An antenna includes a central loop and four adjacent coplanar eccentric loops. The central loop creates a magnetic field that is essentially perpendicular to the antenna. The centres of gravity of the four eccentric loops are essentially located on the periphery of the central loop and the eccentric loops are supplied in such a way as to predominantly create a rotating field in a plane parallel to the plane of the antenna. The eccentric loops can be associated in pairs of non-adjacent loops in such a way as to generate electromagnetic fields of opposite phases in the respective pair. In this way, the two loops of a pair can be connected such that the same current flows through them in opposite trigonometric directions. A radiofrequency generator can supply first and second excitation signals alternately on two outputs, respectively to the central loop and to the eccentric loops.

摘要： A transponder of a contactless data exchange system includes a unit to receive and transmit data provided with at least one first antenna loop and at least one second antenna loop in order to carry out a coupling with a reader. The transponder includes a phase shifter to shift a signal coming from the second loop by a phase shift of K*π, K being an odd integer greater than 0, to produce a phase shifted signal. The transponder includes an adder, to add a signal coming from said first loop and the phase shifted signal to produce a sum signal. The transponder also includes a unit to authorize or prevent a data transmission, depending on the sum signal. A reader of a contactless data exchange system includes a data sending/receiving unit provided with at least one antenna loop, at least one other antenna loop, and a phase shifter.
