ABSTRACT:
The invention concerns a method for adjusting frequency tuning of a resonant circuit with turns having a regular spacing generating stray inter-turn capacity. The adjusting of the frequency tuning of the resonant circuit is performed, at the level of the stray inter-turn capacity, by varying the regular spacing of adjacent turns on at least one zone of the antenna. The invention uses this adjusting method for producing an adjusted antenna for a resonant circuit, the resonant circuit and a non-contact product. The invention concerns a device programmed for antenna production and/or definition.
