Abstract

1 / 1 resumo “antena, e, mã‰todo para fabricaã‡ãƒo de uma antena ” uma antena compreendendo duas ou mais sub-redes de antena substancialmente idãªnticas (3a, 3b), cada uma compreendendo uma pluralidade de elementos de irradiaã§ã£o da antena separados (6a, 6b) conectados a uma porta de entrada/saã­da do sinal de radiofrequãªncia (rf) comum (4a, 4b). os elementos de antena separados sã£o conectados ã  porta de entrada/saã­da do sinal de rf atravã©s dos respectivos divisores de potãªncia do sinal de rf (8a, 8b). uma variaã§ã£o nos valores da proporã§ã£o de repartiã§ã£o de potãªncia, e/ou da reflexividade do sinal de rf de entrada, a e/ou do equilã­brio de fase de correspondentes divisores de potãªncia de sinal das duas ou mais sub-redes de antena ã© suficiente para proporcionar uma proporã§ã£o de cancelamento superior a 40 db. alternativamente, os elementos de antena separados sã£o conectados ã  porta de entrada/saã­da do sinal de rf atravã©s dos respectivos trajetos de transmissã£o (7a, 7b) e uma variã¢ncia em valores dos comprimentos dos trajetos de transmissã£o de correspondentes trajetos de transmissã£o de sinal de duas ou mais sub-redes de antenas ã© suficiente para proporcionar uma proporã§ã£o de cancelamento superior a 40 db.
