Abstract

"MéTODOS E APARELHOS PARA FORMAR UMA ANTENA DE REDE EM FASE EM ONDA DE MILìMETRO". A invenção refere-se a um sistema de antena de rede em fase que tem uma placa de circuito impresso de microlinha de fita de rede de distribuição de guia de linha corporativo. A placa de circuito impresso de microlinha de fita recebe energia de onda eletromagnética (EM) de uma placa de entrada de rede de distribuição de guia de onda 1X4 e distribui a energia de onda EM para 524 elementos radiantes. A placa de circuito de microlinha de fita permite um espaçamento extremamente compacto de elementos radiantes de antena independentes que não seda possível com um guia de onda cheio de ar retangular. O sistema de antena permite a operação em freqüências de onda de milímetro, e especificamente a 44 GHz, e sem requerer a utilização de uma pluralidade de tabelas de consulta para vários retardos de fase e amplitude, que de outro modo sedam requeridos com a estrutura de distribuição de guia de onda cheia de ar. O sistema de antena pode ser utilizado em freqüências de onda de milímetro, e em conexão com o protocolo de comunicação MILSTAR, sem a necessidade de conhecer, com antecedência, a próxima freqüência de salto de feixe empregada pelo protocolo MILSTAR.
