Abstract
Methods, systems, and apparatuses for receiving signals from communications satellites are disclosed. An antenna unit for receiving signals transmitted from a plurality of communications satellites at a plurality of orbital slots, in accordance with one or more embodiments of the present invention comprises a first reflecting surface, a frequency selective reflective surface, and a plurality of low noise block down converters with feedhorns (LNBFs), wherein at least a first LNBF is placed on the antenna unit in a first location and receives at least first signals at a first frequency band from a first orbital slot and at least a second LNBF is placed on the antenna unit at a second location and receives at least second signals at a second frequency band from the same orbital slot, wherein the first signals reflect from the first reflecting surface and transmit through the frequency selective surface and the second signals reflect from the first reflecting surface and also reflect from the frequency selective surface.
