Abstract

"VARREDURA DE ANTENA DE AUTODIRECIONAMENTO". Uma antena de autodirecionamento possui um refletor, uma alimentação ou um sub-refletor e uma pluralidade de escoras de suporte acopladas entre o refletor e o braço de lança e suportando a alimentação ou o sub-refletor. Pelo menos um atuador é operativamente acoplado com as escoras de suporte para ajustar a posição da alimentação ou do sub-refletor em relação ao refletor de modo a seletivamente ajustar um/ou ambos entre a elevação e o azimute do feixe de um eixo do feixe principal da antena.
