Abstract: The principle and mathematical model of satellite multiple-beam antenna are introduced.Then it is proved that pattern synthesis is essentially an optimizationproblem and the two feasible optimization algorithms,the least pth algorithm and Minimax algorithm ,are used to synthesize patterns for a square area and Chinese map respectively.Finally the simulation results of these two algorithms are presented and discussed in detail.
