摘要： A method for sending data by inductive coupling includes: extracting an antenna signal from an antenna circuit, extracting from the antenna signal a first periodic signal, producing a second periodic signal by way of a synchronous oscillator, placing the oscillator in a free oscillation mode and applying to the antenna circuit the second periodic signal, modifying the impedance of the antenna circuit, restoring the amplitude of the antenna signal, then resynchronizing the oscillator on the first periodic signal.

摘要： In a general aspect, a method can include producing, by an inductive antenna circuit, a first periodic signal that is based on an alternating external magnetic field; producing, by an oscillator circuit, a second periodic signal that is based on the first periodic signal; and transmitting, in correspondence with a data-carrying modulation signal, a sequence of data bits. The transmitting can include sequentially and repetitively: applying, with the oscillator circuit operating in a free oscillation mode, the second periodic signal to the inductive antenna circuit; and inhibiting, with the oscillator circuit operating in a synchronous oscillation mode, application of the second periodic signal to the inductive antenna circuit. The synchronous oscillation mode of the oscillator circuit can cause the second periodic signal to be synchronized to the first periodic signal.

摘要： In a general aspect, a mobile communications apparatus can include a housing and inductive coupling communication circuitry configured to communicate in peer-to-peer mode with a like apparatus. The inductive coupling communication circuitry can include a communication controller and an inductive antenna. The inductive antenna can have at least one loop arranged in series between a first connection point and a second connection point and be proximate to a back wall of the housing. The inductive antenna can be, when the mobile communications apparatus is placed back-to-back in longitudinal and latitudinal alignment with a like mobile communications device, asymmetric with a like inductive antenna of the like mobile communications device, where a ratio of a sum of respective surface areas of mutually opposite surfaces of loops of a same rank of the inductive antenna divided by a sum of respective surface areas of the like inductive antenna is 0.8 or less.
