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.
