Abstract

Patente de Invenção:<B>"SISTEMA DE ANTENA SETORIZADO DE ALTO DESEMPENHO QUE UTILIZA DISPOSITIVOS DE ALIMENTAçãO DE BANDA LARGA DE BAIXO PERFIL"<D>. Um sistema de antena setorizado tem uma ou mais lentes dielétricas (20), cada uma tendo uma superfície e dois ou mais dispositivos de alimentação de antena de baixo perfil (21). Pelo menos um dos dispositivos de alimentação irradia os sinais para dentro das ditas lentes que emergem como feixes direcionais separados, e/ou as lentes recebem os sinais que entram de diferentes direções e os focaliza por sobre diferentes dispositivos de alimentação de antena. Os dispositivos de alimentação do sistema de antena setorizado são dispositivos de alimentação de banda larga de perfil baixo, tais como as redes dipólo log periódicas ou as antenas de fenda cónica. Orientações especiais de projeto são dadas para a sua utilização com uma lente. Em adição, um método para reduzir a freq³ência de corte da antena de fenda cónica é mostrado.
