Abstract

"SISTEMA DE ANTENAS PARA TRANSMITIR E RECEBER SINAIS EM DUAS BANDAS DE FREQUêNCIAS, E, APARELHO DE TRANSMISSãO E RECEPçãO MóVEL DE MULTICANAL". Sistema de antenas para transmitir e receber sinais em duas bandas de freq³ências é pequeno, muito eficiente e capaz de, simultaneamente, transmitir e receber sinais em duas bandas de freq³ências, ao mesmo tempo em que assegura alto desacoplamento entre as duas. Duas ou mais antenas de microtiras (1A, 1B, 1C, 1D) são dispostas em um substrato dielétrico único (2), dotado de um plano de terra (3), equipado com sua própria conexão de alimentação (6) e disposto de modo a minimizar o acoplamento recíproco.
