Abstract

SISTEMA E METODO PARA CASAMENTO DE ANTENA DE BANDA DUAL São apresentados um sistema de casamento de antena de banda dual e um método para casamento em impedância de banda dual. O método compreende: aceitar uma impedância dependente da freqüência de uma antena; e fornece seletivamente uma casamento em impedância conjugada para a antena ou em uma primeira e uma segunda bandas de comunicação, ou em uma terceira e uma quarta bandas de comunicação. Mais especificamente, o método compreende: sintonizar um primeiro circuito de sintonização em uma primeira freqüência; e sintonizar simultaneamente um segundo circuito de sintonização em uma segunda freqüência. Em resposta, um casamento conjugado é fornecido à antena na primeira banda de comunicação em resposta à primeira freqüência. Simultaneamente, a antena é casamento na segunda banda de comunicação em resposta á segunda freqüência. Quando o primeiro circuito de sintonização é sintonizado em uma terceira freqüência e o segundo circuito de sintonização é sintonizado em uma quarta freqüência, então casamentos conjugados são fornecidos para as terceira e quarta bandas de comunicação, em resposta às terceira e quarta freqüências, respectivamente.
