Abstract

Patente de Invenção:<B>"ANTENA COM MATRIZ DE MICROFITA"<D>. Uma antena de microfita (10) possui duas camadas dielétricas (12, 14) vinculadas e uma matriz de fita condutora (20, 22, 24, 26) sendo espaçadas para definir uma abertura (30, 32, 34) entre cada par de fitas adjacentes. Um plano de solo condutivo (16) é disposto em um primeiro lado externo (12a) das duas camadas dielétricas vinculadas (12, 14) e uma matriz de entalhes de mediações (40, 42, 44) são dispostos em um segundo lado externo (14a) da duas camadas dielétricas vinculaas (12, 14) cada um dos entalhes é posicionado sobre uma abertura correspondente, a matriz de entalhes sendo espaçadas de uma abertura (52, 54) entre cada par de entalhes adjacentes (40, 42, 44). Em resposta a energia eletromagnética, uma onda de duração de alta-ordem é induzida na antena e feixe direcionado e transmiido do e/ou recebido na antena.
