Abstract

Red conformadora de haces para agrupaciones de antenas basada en matrices ópticas de elementos desfasadores/retardadores fijos. Una red conformadora de haces basada en matrices de Butler ópticas sobre la que se aplican una serie de modificaciones destinadas a aumentar el número de posibles haces generados por la matriz, aprovechar de un modo inmediato y simple la capacidad multihaz intrínseca a la misma, dotar a la arquitectura de la capacidad de ajustar la posición angular de los posibles haces, simplificar de manera notable el diseño final de la red conformadora y dotar a la red de la capacidad de generar simultáneamente determinados frentes de fase y sus opuestos. La invención propuesta es asimismo aplicable a otras estructuras de matriz óptica de elementos desfasadores/retardadores fijos (como las matrices de Blass o Rotman) y, en general, a otras arquitecturas de conformación heterodina.Beam shaping network for antenna groupings based on optical matrices of fixed phase shifters / retarders. A beam shaping network based on optical Butler matrices on which a series of modifications are applied aimed at increasing the number of possible beams generated by the matrix, taking advantage of the intrinsic multibeam capacity of the matrix immediately and simply, providing the architecture of the ability to adjust the angular position of the possible beams, significantly simplify the final design of the shaping network and provide the network with the ability to simultaneously generate certain phase fronts and their opposites. The proposed invention is also applicable to other optical matrix structures of fixed phase shifters / retarders (such as Blass or Rotman matrices) and, in general, to other heterodyne conformation architectures.
