Abstract

Patente de Invenção: <B>''ATENUADOR REGULáVEL''<D>. Um atenuador, regulável de modo bastante simples, consiste em uma linha plana (1), cuja largura (w) acha-se reduzida em uma seção com um comprimento (L) de cerca da metade do comprimento de ondas de operação do atenuador. Nessa seção, no mínimo em um lado ao lado da linha (1), acha-se colocada uma camada (2, 3) de um material de atenuação. Uma atenuação desejada pode ser ajustada através de alteração da largura (b) da camada de material de atenuação (2, 3).
