Abstract:
1. 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 is 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) executing expansion according to the equation to achieve expansion of  in which expansion coefficients of C analyzing the radiation waveforms of the reflector according to the expansion coefficients of C 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, C wherein the values of the expansion coefficients C wherein the values of C nm and D nm are zero when corresponding variables n and m are not listed.
