Abstract

FILTRO ELIMINADOR DE BANDA" . Filtro eliminador de banda (300) implementado por ressonadores coaxiais para filtrar os sinais de antena, particularmente em estações base de redes de comunicação móvel. O ponto inicial é uma estrutura com uma linha de transmissão e ressonadores coaxiais acoplados eletromagneticamente em paralelo a esta, e cujas freqüências naturais dos ressonadores diferem um pouco entre si. Os ressonadores (R1, R2,R3) f ormam um alojamento ressonador condutivo unitário (310), cujo espaço interno foi dividido em cavidades ressonadoras pelas paredes condutoras de partição. Na invenção, o condutor central (321) da linha de transmissão é colocado dentro do alojamento do ressonador, de maneira a percorrer todas as cavidades do ressonador, o alojamento funcionando ao mesmo tempo como condutor externo da linha de transmissão. As cavidades do ressonador fazem, portanto, parte da cavidade da linha de transmissão. Quando um campo eletromagnético de mesma freqüência que a freqüência natural de um ressonador ocorre na linha de transmissão, o ressonador em questão começa a oscilar, fazendo o campo refletir de volta na direção da fonte de alimentação. São estabelecidas ao mesmo tempo, a potência da ressonância e a amplitude de sua faixa de influência, por exemplo, escolhendo adequadamente a distância entre o condutor interno (301) do ressonador e o condutor central (321) da linha de transmissão, O número de peças estruturais e de uniões metálicas no filtro eliminador de banda são relativamente pequenos. Portanto, ocorre menos intermodulação no filtro que nos filtros correspondentes conhecidos. Outras idades funcionais também podem ser facilmente integradas na estrutura do filtro.
