Abstract

''DISPOSITIVO DE ANTENA LAMINAR'' Uma antena laminar que compreende uma placa de aterramento condutora 1, uma lâmina condutora 2 arranjada em paralelo acima de dita placa de aterramento condutora 1, um condutor de alimentação 6 para alimentar dita antena laminar, e um material substrato dielétrico 5 arranjado entre a placa de aterramento condutora 1 e a lâmina condutora 2, na qual o condutor de alimentação 6 é conectado a um lado do material substrato dielétrico 5 e a lâmina condutora 2 é conectada a um outro lado de dito material substrato elétrico 5. O material dielétrico fornecido entre a lâmina e a placa de aterramento serve para aumentar a separação de polarização cruzada e na combinação da impedância da antena. Assim, a separação de polarização cruzada e a largura de banda aumentada podem ser conseguidas dentro da antena laminar de uma maneira simples e efetiva em custo. Além disto, uma sonda ordinária de alimentação e cabos coaxiais podem ser utilizados e pequena capacitância precisa pode ser implementada.
