Abstract

"ANTENA DE LEITOR EM UM SISTEMA DE IDENTIFICAçãO OU DE ACESSO A UMA ZONA DE ACESSO CONTROLADO". Antena de leitor em um sistema de identificação ou de acesso a uma zona de acesso controlado compreendendo um leitor destinado a detectar sinais eletromagnéticos de resposta proveniente de um objeto portátil sem contato tal como um cartão de tipo ISO ou um tíquete descartável (46), os sinais eletromagnéticos de resposta sendo emitidos por uma antena (48) situada no objeto portátil em resposta a recepção de sinais eletromagnéticos emitidos pela antena de leitura quando o portador do objeto portátil apresenta o dito objeto portátil diante do dito leitor. A antena compreende n grupos de espiras (20, 22, 24) dispostas em série nas quais cada grupo de espiras k-1 comporta um numero de espiras N~ k-1~, inferior ao número de espiras N~ k~ do grupo de espiras k (com k variando de 2 a n) e é afastada do grupo de espiras k por uma distância D~ k-1~, superior a um valor predefinido, as espiras de todos os grupos sendo enroladas no mesmo sentido."READER ANTENNA IN AN IDENTIFICATION SYSTEM OR ACCESS TO A CONTROLLED ACCESS ZONE". Reader antenna in a controlled access zone identification or access system comprising a reader for detecting electromagnetic response signals from a non-contact portable object such as an ISO type card or a disposable ticket (46); electromagnetic response signals being emitted by an antenna (48) located on the portable object in response to reception of electromagnetic signals emitted by the reading antenna when the portable object carrier presents said portable object in front of said reader. The antenna comprises n sets of turns (20, 22, 24) serially arranged in which each turn group k-1 has a number of turns N ~ k-1, less than the number of turns N ~ k ~ of the group of turns k (with k ranging from 2 an) and is spaced from turns group k by a distance D ~ k-1 ~ greater than a preset value, turns of all groups being wound in the same direction.
