Abstract

Un método de demodulación de señales de campo electromagnético (H) inducidas en una antena principal (4) de un lector por un transpondedor sin contacto, comprendiendo dicho método una etapa de detección de las señales del transpondedor en momentos determinados, caracterizado porque los momentos determinados de detección de las señales del transpondedor están sincronizados con una fase del campo electromagnético (H), o con un valor representativo de dicha fase.
