| Abstract: | Muhi - beam antenna is widely used in low earth orbit(LEO) satellite systems. Spot - beam de-sign of on - board multi - beam antenna is discussed, an optimized method adopting optimization theory for spot -beam design is proposed to balance the receiving gain of each spot -beam covering area, analysis of the optimized method for Globalstar system is given, and higher satisfaction of the proposed method is proved. |
