Abstract

"TRANSMISSORES PARA TRANSMITIR UMA ONDA DE SINAL MODULADO POSSUINDO UMA POLARIZAçãO LINEAR DE ORIENTAçãO SELECIONADA, PARA TRANSMITIR SINAIS DE UMA POLARIZAçãO SELECIONADA EM UM SISTEMA ACESSO MúLTIPLO POR DIVISãO DE TEMPO E PARA TRANSMITIR UMA ONDA DE POLARIZAçãO DESEJADA E SUPRIMIR UMA ONDA E POLARIZAçãO INDESEJADA" Um transmissor provê uma onda de rádio com polarização selecionável. O transmissor inclui alimentadores de antena que geram ondas de rádio ortogonais possuindo uma polarização não-linear que corresponde às relações de fase selecionável de um primeiro e segundo sinais de modulação. Uma combinação espacial das ondas de rádio não-lineares para produzir uma onda de rádio polarizada linearmente que tem uma orientação correspondente a uma relação de fase selecionada.
