Abstract
a invenção se refere a um cartão com chip com funcionamento sem contato, destinado a se comunicar com um leitor de cartão com chip que funciona a uma frequência de ressonância f0?, o dito cartão com chip sendo provido de um corpo de cartão que integra pelo menos uma antena conectada em série ou em paralelo com uma capacidade, os valores das indutâncias das antenas e o valor da capacidade sendo escolhidos para obter uma frequência de ressonância f0 suficientemente afastada da frequência do sinal emitido pelo leitor para limitar a comunicação de radiofrequência com o leitor, de modo que o cartão com chip se encontra por princípio discordante em relação ao leitor, e os valores das ditas indutâncias e capacidade sendo por outro lado escolhidos para que a conexão em paralelo de uma capacidade suplementar cd predeterminada leve a frequência de ressonância do cartão para a proximidade da frequência f0? do sinal emitido pelo dito leitor de modo que o cartão com chip se encontre em harmonia com o leitor, caracterizado pelo fato de que o cartão com chip compreende uma antena booster (20) provida de uma antena principal de indutância u e de uma antena concentrador de indutância l2, conectadas em série ou em paralelo com a capacidade c, e pelo fato de que os valores de l1, l2 e c são escolhidos por um lado para obter a dita frequência de ressonância f0, e por outro lado para que a conexão em paralelo da dita capacidade cd predeterminada leve a frequência de ressonância do cartão para a proximidade da dita frequência f0? do sinal emitido pelo dito leitor.
