Abstract
Patente de Invenção: <B>"ANTENA DE ESTAçãO DE BASE PARA POLARIZAçãO DUPLA''<D>. Um sistema de antena melhorado para a transmissão e a recepção de sinais eletromagnéticos, que compreende um contraplano que tem um comprimento e um eixo vertical ao longo do comprimento. Uma pluralidade de elementos radiantes de dipolo se projetam para fora a partir de uma superfície do contraplano. Cada um dos elementos inclui um par ortogonal equilibrado de dipolos alinhados em um primeiro e em um segundo ângulos predeterminados em relação ao eixo vertical, formando pares de dipolo cruzado. Uma rede de alimentação desequilibrada se estende ao longo do contraplano e é conectada aos elementos radiantes. Um balun de placa de circuito impresso é fixado a cada um dos dipolos. A antena também pode incluir um elemento parasita posicionado ao longo do eixo vertical de modo que campos eletromagnéticos primários induzam correntes no elemento parasita, essas correntes induzidas reirradiem campos eletromagnéticos secundários, os quais cancelam porções dos campos eletromagnéticos primários, desse modo melhorando o isolamento.
