Abstract
Patente de Invenção: <B>"CIRCUITO DE APREFEIçOAMENTO DE ISOLAMENTO PARA UMA ANTENA DE DUPLA POLARIZAçãO<D>". Circuito de aperfeiçoamento de isolamento para uma antena de dupla polarização, a antena de dupla polarização consistindo de uma antena, tanto de transmissão como de recepção, para simultaneamente transmitir um sinal de transmissão e receber um sinal de recepção, no qual as antenas de transmissão e recepção são configuradas de modo a serem matuamente ortogonais, quer seja pela orientação física, quer seja pela orientação elétrica, a fim de reduzir a intensidade na qual o sinal de tansmissão é captado pela antena de recepção. O circuito de aperfeiçoamento de isolamento reduz o nível do sinal de transmissão que aparece na porta de saída da antena de recepção com a provisão de um sinal de transmissão retardado por tempo que destrutivamente interfere co o sinal de transmissão captado pelo elemento de recepção. O retardo de tempo é provido através do dimensionamento de um conduto usado para transportar o sinal de transmissão para a porta de saída da antena de recepção, ou para a antena de recepção e depois para a porta de saída, o dimensionamento incluindo não apenas a seleção de um comprimento do condutor, mas também, opcionalmente, e dependendo do tipo de condutor, o ajuste de quaisquer elementos capacitivos ou indutivos do condutor.
