Abstract

Un sistema de conjunto circular alimentado por matriz incluye una pluralidad de antenas, una pluralidad de matrices de azimut en comunicacion con las antenas, y una pluralidad dematrices de elevacion en comunicacion con las matrices de azimut. El sistema de conjunto forma haces M x N, donde M es el numero de haces de azimut, y N es el numero de haces de elevacion. En otra forma de realizacion, a través del uso de una matriz de Shelton-Butler o de Butler que incluye una pluralidad de híbridos, el sistema da salida a patrones de radiacion con forma de disco omni-direccionales que están aislados entre sí cuando se da entrada a una senal de comunicacion en el sistema. Incluso en otra forma de realizacion, el sistema utiliza una red de formado de haz que incluye dos matrices de Shelton-Butler. Una primera de las matrices de Shelton-Butler crea haces con forma de disco omni-direccionales que están aislados entre sí, y una segunda matriz de Shelton-Butler crea multiples haces direccionales en un plano de azimut.
