Abstract

Las características descritas se refieren, en general, al ajuste de un patrón de antena nativo de un satélite para adaptar comunicaciones mediante el satélite. Por ejemplo, un satélite de comunicaciones puede incluir una antena que tiene un conjunto de matriz de alimentación, un reflector, y un accionador lineal acoplado entre el conjunto de matriz de alimentación y el reflector. El conjunto de matriz de alimentación puede tener múltiples alimentaciones para comunicar señales asociadas a un servicio de comunicaciones, y el reflector puede configurarse para reflejar las señales transmitidas entre el conjunto de matriz de alimentación y uno o más dispositivos objetivos. El accionador lineal puede tener una longitud ajustable, o de otra manera proveer una posición ajustable entre el conjunto de matriz de alimentación y el reflector. Mediante el ajuste de la posición del conjunto de matriz de alimentación con respecto al reflector, el satélite de comunicaciones puede proveer un servicio de comunicaciones según múltiples patrones de antena nativos.
