Abstract
"ANTENA PARA RECEPçãO E/OU TRANSMISSãO DE ONDAS ELETROMAGNéTICAS". Uma antena para recepção e/ou transmissão de ondas eletromagnéticas, compreendendo um arranjo de elementos de antena incluindo pelo menos uma carreira longitudinal de elementos de antena (7) localizados a uma distância (d) um do outro, cada carreira de elementos de antena sendo adaptada para receber e/ou transmitir um feixe polarizado dual incluindo dois canais isolados mutuamente, separados. Ao longo de cada carreira longitudinal de elementos de antena, nas proximidades do intervalo entre o respectivo par de elementos de antena adjacentes, preferivelmente ao lado da linha de centro (C) da carreira, são dispostos elementos parasitas (8a, 8b) servindo para influenciar o acoplamento mutuo entre ditos elementos de antena adjacentes de tal forma a aperfeiçoar o isolamento entre os canais separados.
