Abstract
"ANTENA DOWNTILT ELéTRICA VERTICAL". Uma antena de estação base sem fio de polarização dupla que implementa o downtilt elétrico vertical e redução de lóbulo lateral usando um circuito de manobra de feixe que inclui um divisor de potência variável e uma rede de formação de feixe multi-feixes. O divisor de potência variável inclui um elemento de controle ajustável simples para dividir um sinal de tensão de entrada em um par de sinais direcionadores de tensão de amplitude complementar que exibem fase combinada e retardo de fase constante no divisor de potência variável. A rede formadora de feixes é configurada como um módulo de microfita com enlace de canto e dois lados, montada em um painel principal que suporta os elementos de antena em uma coluna vertical organizada em subconjuntos, de maneira a implementar a redução do lóbulo lateral. A rede de distribuição de potência que liga a rede de manobra de feixes aos elementos de antena, implementa a redução de lóbulo lateral e o viés de inclinação de feixe por mudança coordenada de fase implementada por ajuste do comprimento de traço do meio de transmissão.
