Abstract

a presente invenção refere-se a uma antena, que compreende um dispositivo reflexivo, pelo menos duas matrizes de radiação cujas bandas de operação estão em uma primeira banda de frequência predeterminada, e múltiplos radiadores parasitas. cada uma das pelo menos duas matrizes de radiação compreende múltiplos elementos de radiação. cada uma das pelo menos duas matrizes de radiação está disposta eletricamente no dispositivo de reflexão ao longo de uma direção longi-tudinal do dispositivo de reflexão. os múltiplos radiadores parasitas estão dispostos entre duas matrizes de radiação adjacentes das pelo menos duas matrizes de radiação. a presente aplicação pode ser em-pregada para reduzir uma largura de feixe horizontal de uma antena de múltiplas matrizes.
