Abstract
Una configuración de antena adecuada para satélites LEO/MEO incluye una variedad de lentes (32) donde cada lente tiene una variedad de antenas de alimentación (42) ubicadas con respecto a la lente (32). La lente (32) tiene una primera superficie (40) y una segunda superficie (38). La variedad de antenas de alimentación (42) se disponen en una superficie curva (44). Cada una de las diversas antenas de alimentación (42) genera un rayo (22) que tiene una distribución de fase. Las distribuciones de fase tienen una relación de fase predeterminada con una primera superficie (40) y preferentemente la segunda superficie (38). Esto permite a la lente (32) transmitir y recibir una señal con una distribución de fase deseada a través de una sección transversal del rayo. Las rayos de las diversas lentes (32) se entrelazan en el suelo para formar un recubrimiento contiguo con múltiples puntos de rayo que se solapan.
