US Patent 7102585 Integrated feed horn device

An integrated feed horn device including three sets of integrally formed feed horn devices is provided. The integrated feed horn device may receive satellite signals reflected by a single parabolic reflector antenna, wherein the satellite signals are transmitted by three satellites separated by small angles. The integrated feed horn device may comprise a first waveguide, a second waveguide and a third waveguide, wherein the first waveguide, the second waveguide and the third waveguide may be adopted for receiving a first satellite signal, a second satellite signal, and a third satellite signal. Each of the satellite signals described above is transmitted by different satellites.
