Abstract

"ANTENA DE EMISSãO E/OU DE RECEPçãO DE ONDAS ELETROMAGNéTICAS E APLICAçãO DA MESMA". Antena de emissão e/ou recepção de ondas eletromagnéticas (10) do tipo que compreende um fio disposto em espiral em um plano, a dita espiral possuindo pelo menos duas espiras; a dita antena sendo caracterizada pelo fato de que ela compreende pelo menos um corte (12) com o objetivo de diminuir a capacidade inter-espiras. Uma tal antena é utilizada em um sistema' de comunicação sem contato no qual um leitor transmite sinais eletromagnéticos para um objeto portátil ( cartão ou bilhete ) de maneira a poder identificar o possuidor do objeto portátil quando esse último transmite em retorno sinais de identificação para o dito leitor.
