Abstract

"SISTEMAS DE ANTENAS E MéTODO DE OPERAçãO DE REDE DE COMUNICAçõES SEM FIOS". Sistema de antena, que incorpora, pelo menos, duas pluralidade de antenas 12, 27, dispostas circunferencialmente numa relação lado a lado em torno de uma torre monopolo 15. A direção do feixe principal do padrão de radiação que emana de cada antena 10 pode ser ajustado remotamente, quanto à elevação e/ou azimute. A direção do feixe principal do padrão de radiação que emana de antenas adjacentes 10 pode ser variada independentemente. As antenas podem ser particionadas em um ou mais grupos espaçados verticalmente 12, 27, cada um dos quais está disposto em torno de uma circunferência da torre monopolo 15.
