Multi-beam-reflector dish antenna and method for production thereof

A multi-beam-reflector dish antenna system comprising:

• a reflector for simultaneously receiving signals from a plurality of satellites;
• and
• at least a first low noise block with integrated feed (LNBF) module for receiving focused waves,
• in which the reflector formed according to the following steps of:
• providing the reflector having N-th order curve surface where the value of factor N equals to 2.1 returned by F(x)n+F(y)n=F(z);
• executing expansion according to the equation to achieve expansion of
• 2 z ⁡ ( t , φ ) = ∑ 0 n ⁢ ∑ 0 m ⁢ [ C ⁢ ⁢ n ⁢ ⁢ m ⁢ ⁢ cos ⁢ ⁢ n ⁢ ⁢ φ + D ⁢ ⁢ n ⁢ ⁢ m ⁢ ⁢ sin ⁢ ⁢ n ⁢ ⁢ φ ] ⁢ F m n ⁡ ( t ) ,
• in which expansion coefficients of Cnm and Dnm are variables;
• analyzing the radiation waveforms of the reflector according to the expansion coefficients of Cnm and Dnm;
• synthesizing the radiation waveforms of the reflector to generate a corresponding radiation pattern;
• and
• acquiring the multi-beam-reflector dish antenna according to the expansion coefficients, Cnm and Dnm, and the radiation pattern.
