Abstract

"FILTRO DE PASSAGEM DE FAIXA COM RESPOSTA PSEUDOELìPTICA". A invenção propõe um filtro de plano-H com irises indutivas que apresenta uma resposta quase elíptica enquanto retém a mesma compacidade que um filtro tendo uma resposta Chebyshev. A invenção torna ainda possível utilizar-se um grande número de zeros de transmissão. Para essa finalidade, é proposto um filtro de guia de onda compreendendo pelo menos uma cavidade (4) delimitada por pelo menos duas irises indutivas (7) . O filtro compreende ainda pelo menos uma inserção flutuante (1) colocada em uma das irises indutivas (7). A invenção também é um processo para fabricar o filtro de guia de onda que incorpora pelo menos uma inserção.
