Abstract

"MéTODO PARA CONFIGURAR AS CARACTERìSTICAS DE IRRADIAçãO DE UMA ANTENA, ANTENA COM CARACTERìSTICAS DE IRRADIAçãO CONFIGURáVEIS, APARELHO COMPREENDENDO UMA ANTENA, ESTAçãO BASE DE RáDIO, REDES DE TELECOMUNICAçõES, E, PRODUTO DE PROCESSAMENTO DE DADOS". As características de irradiação de uma antena são feitas configuráveis, incluindo na antena (A) uma pluralidade de elementos de irradiação e associando a cada um dos ditos elementos de irradiação uma respectiva cadeia para processar o sinal na transmissão e/ou recepção, compreendendo: - um módulo para ponderar sinais digitais (34a, 34b, 34c, 34d; 36a, 36b, 36c, 36d) capaz de aplicar a um sinal digital pelo menos um respectivo coeficiente de ponderação, e - um conjunto de conversão de antena (16 a 26) interposto ao módulo para ponderação de sinais digitais e um dos elementos de irradiação da antena, o conjunto de conversão de antena operando sobre um sinal digital sobre o lado do módulo de ponderação de sinal e sobre um sinal analógico, distribuido sobre as cadeias de processamento associadas a cada um dos elementos de irradiação da antena (A), propagado (em transmissão e/ou recepção), enquanto respectivos coeficientes de ponderação são aplicados aos ditos módulos de ponderação de sinal digital (34a, 34b, 34c, 34d; 36a, 36b, 36c, 36d), os ditos coeficientes de ponderação determinando o diagrama de irradiação da antena.
