Abstract

"ANTENA DE BANDA DUPLA PARA UM SISTEMA DE COMUNICAçãO MóVEL". Uma antena de banda dupla para um sistema de comunicação móvel que inclui: um tubo metálico possuindo uma extremidade aberta; uma linha de alimentação coaxial possuindo condutores interno e externo, com uma parte da linha coaxial inserida dentro do tubo metálico, um plano terra conectado a uma parte do tubo metálico oposta à extremidade aberta e ao condutor externo da linha de alimentação coaxial e, uma linha de sinal eletricamente acoplada ao condutor interno e se projetando a partir do tubo metálico na extremidade aberta do mesmo. Preferivelmente, as dimensões do tubo metálico, a linha de alimentação coaxial e a linha de sinal são selecionados de forma que a antena sua impedância coincidindo com a linha de alimentação coaxial através da banda de operação dupla, eliminando dessa forma a necessidade por uma rede de coincidência separada.
