Abstract

"DISPOSITIVO DE LEITURA DE TRANSPONDOR". Dispositivo de leitura (100) que possui um estágio de potência e uma antena de leitura (110) que permitem gerar um campo eletromagnético de excitação de pelo menos um transpondor (10) situado no campo da antena, esse transpondor possuindo uma antena de recepção (11) e meios de comutação associados (12) que lhe permitem modificar o estado da antena de recepção e transmitir assim informações para o dispositivo de leitura por modificação do acoplamento entre a antena de leitura e a antena de recepção. O dispositivo de leitura possui meios de detecção dispostos para reduzir no sinal da antena o ruído ou as flutuações devidos aos componentes eletrónicos do estágio de potência e gerar um sinal útil com base na variação no sinal da antena de leitura,em relação a um sinal de referência, esse sinal de referência sendo representativo do sinal da antena de leitura quando a antena de recepção do transpondor está em um estado predeterminado, o sinal útil sendo representativo das mudanças no estado da antena de recepção.
