Abstract

"APARELHO PARA SUPRIMIR INTERFERêNCIA MúTUA ENTRE ANTENAS". Aparelho para suprimir interferência mútua entre antenas colocadas perto uma da outra, dito aparelho consistindo de pelo menos um elemento supressor alongado (5) de material eletricamente condutor, encaixado entre os irradiadores de antena (11, 21) e disposto em um plano transversal à linha de conexão entre as antenas. O elemento supressor está disposto na direção de irradiação e seu comprimento iguala a um quarto ou um múltiplo de um quarto de um dos comprimentos de onda na faixa de freq³ência das antenas, assim funcionando como um ressonador sintonizado pelo menos à faixa de freq³ência em questão, irradiando em um plano transversal à direção de irradiação das antenas (1,2).
