Patent ID: 7911403

Claim:
An antenna for communicating with a satellite, comprising: a rotating base; main and sub reflectors; a rotating ortho-mode transducer (OMT) located behind said main reflector and configured for polarizing a transmission signal; a waveguide associated with said OMT for conducting said polarized transmission signal toward a feedhorn between said main and sub reflectors; and an actuating unit configured for adjusting a tilting angle of said main reflector in relation to said rotational base while at least one of said waveguide and said sub reflector remain substantially stationary in relation to said rotational base; wherein said feedhorn is configured for radiating said sub reflector with a beam generated from said polarized transmission signal, said sub reflector is configured for redirecting said beam toward said main reflector, said main reflector being configured for projecting said redirected transmission signal as an antenna beam toward the satellite.
