Abstract

"ANTENA NãO BALANCEADA". Uma antena não balanceada tendo um condutor de irradiação e um condutor terra providos com uma abertura predeterminada entre eles, é provida. Pelo menos uma parte predeterminada do condutor terra, a parte predeterminada estando oposta ao condutor de irradiação, é deixada, de fonna que se mantenha funcionando como um pólo para formar uma distribuição de campo eletromagnético próximo junto com o condutor de irradiação oposto ao condutor terra. Ademais, uma parte do condutor terra reduzido, a parte estando perto de uma ponta a uma distância predeterminada da seção de alimentação, inclui um condutor tendo baixa condutividade para obter associação de impedância. Onde o condutor terra é significativamente reduzido, a desassociação de modo ocorre inevitavelmente. Portanto, pelo menos uma parte de um condutor externo de uma linha de alimentação coaxial conectada à seção de alimentação está coberta por um absorvedor de corrente, assim para reduzir poderosamente uma corrente de fuga. Subseq³entemente, o condutor terra pode ser reduzido e a característica de antena pode ser mantida.
