Abstract

"ANTENA DE QUADRO COM PELO MENOS DUAS FREQUêNCIAS RESSONANTES". Uma antena carregada dieletricamente para operação em freq³ências em excesso de 200 MHz inclui uma estrutura de elementos de antena disposta em um núcleo constante dielétrico alto, cujo estrutura de elemento compreende um par de grupos lateralmente opostos de elementos de antena helicoidal. Cada grupo compreende primeiro e segundo elementos mutuamente adjacentes, de larguras diferentes na antena, formadas pelos primeiros elementos de cada grupo e os segundo elementos de cada grupo respectivamente, que ressonam em freq³ências ressonantes respectivas distintas para produzir uma largura de faixa de operação relativamente larga. Os elementos helicoidais de cada grupo definem, entre eles, parte de um canal alongado que possui um comprimento elétrico total na região de n<sym>/2 dentro da faixa de freq³ência de operação para fornecer isolamento entre as trajetórias condutoras em alças. A parte principal de cada tal canal está localizada entre os elementos de modo a minimizar a intrusão nas outras partes condutoras da antena.
