Abstract

"PROCEDIMENTO PARA A CALIBRAGEM DE UMA ANTENA DE GRUPO ELETRôNICA COM COMANDO DE FASE, EM SISTEMAS DE COMUNICAçãO-RáDIO". A presente invenção, refere-se a calibragem de uma antena de grupo comandada por meio de fase em sistemas de comunicação-rádio são, com o emprego de um ponto de referência comum para todos os sinais de referência, irradiados em Downlink pelos elementos de antena individuais da antena de grupo. Os sinais de referência distinguíveis entre si são irradiados juntos e, após a recepção, são separados de forma adequada, no ponto de referência comum.
