摘要:
A tracking antenna system for use in a plurality of discrete radio frequency (RF) spectrums includes a stabilized antenna support configured to direct and maintain the antenna in alignment with a communications satellite; a reflector mounted on the stabilized antenna support, the reflector reflecting radio waves along a first RF path; a first feed for gathering radio waves within a first of the discrete RF spectrums traveling from the reflector; a sub-reflector movable between first and second positions, the first position outside the first RF path and the second position in the first RF path to redirect radio waves traveling from the reflector along the first RF path to a second RF path; a second feed for gathering radio waves within a second of the discrete RF spectrums redirected along the second RF path; and an actuator for moving the sub-reflector between the first and second positions.
摘要(中):
用于多个离散射频(RF)频谱的跟踪天线系统包括被配置为引导和维持天线与通信卫星对准的稳定天线支架; 安装在所述稳定天线支架上的反射器,所述反射器沿着第一RF路径反射无线电波; 用于在从反射器行进的第一离散RF频谱内收集无线电波的第一馈送; 在第一和第二位置之间移动的子反射器,第一RF路径外的第一位置和第一RF路径中的第二位置,以将从反射器行进的无线电波沿着第一RF路径重定向到第二RF路径; 用于在沿着第二RF路径重定向的离散RF频谱的一秒的范围内收集无线电波的第二馈送; 以及用于在第一和第二位置之间移动副反射器的致动器。
