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.
