<p>Described herein is a transponder (14) intended to be applied to a metal or electrically conductive structure and required to operate, when applied to the structure, at a nominal frequency (F1). The transponder (14) is designed to operate, when not applied to the structure, at a shifted frequency (F1+FS) which is shifted from the required nominal frequency (F1) of a frequency shift (FS) which depends on a parasitic capacitance which is present between the structure and the transponder (14) when the transponder (14) is applied to the structure, whereby, when applied to the structure, the transponder (14) operates at the required nominal frequency (F1).</p> |
