Abstract

"CIRCUITOS DE ALIMENTAçãO PARA CONECTAR UMA ANTENA A UM CIRCUITO DE COMUNICAçõES, PARA CONECTAR UMA ANTENA A UM ALIMENTADOR, PARA UMA ANTENA, E, RESSONANTE PARALELO PARA CONECTAR UMA ANTENA A UM ALIMENTADOR" Um circuito de alimentação conecta uma antena a um circuito de comunicações para obter uma largura de faixa de operação aumentada. O circuito de alimentação inclui um "balun" dobrado possuindo uma porta balanceada configurada para conectar a antena e uma porta não balanceada configurada para conectar ao circuito de comunicação. Em adição, uma capacitância de ressonância é conectada através da porta balanceada do "balun" dobrado. A capacitância de ressonância possui um valor que provê ressonância com uma indutância do "balun", de tal modo que a largura de faixa de operação do circuito de alimentação e antena combinados é aumentada.
