Abstract: A device for an electronic cigarette. The device includes an enveloping element defining an interior, and an authentication device arranged in or on the enveloping element. The authentication device includes a planar loop antenna, and an authentication logic coupled to the planar loop antenna and configured to provide an authentication of the device vis-à-vis a control element of the electronic cigarette. The planar loop antenna is arranged in rolled form in the interior of the enveloping element or on the exterior of the enveloping element. The loop antenna comprises conduction sections in two opposite regions of the planar loop antenna, which extend in the longitudinal direction of the rolled loop antenna. The conduction sections of the opposite regions are arranged such that they are adjacent or overlap one another, with a result that their respective fields mutually compensate for one another at least partly.

Abstract: A transponder unit for the contactless transmission of modulated data to a reader is provided. The transponder unit includes a clock generator configured to generate a clock signal and to synchronize the clock signal in a synchronization mode, on the basis of a signal received from the reader, and a modulator, the modulator configured to modulate data on the basis of the clock signal from the clock generator. The modulator is configured to generate a modulation pause by masking out at least one modulation component, the modulation component being smaller than a modulation pulse. The modulator is further configured to send the signal for starting the synchronization mode to the clock generator during this modulation pause.
