In this paper linearly constrained minimum variance (LMCV) algorithm is originally applied to pattern synthesis for satellite multiple-beam antenna.Under constraint on main lobe level

the pattern of antenna is synthesized by minimizing the radiation power of antenna.Unlike conventional iterative algorithms

LCMV is an analytic algorithm

which makes it more accurate and efficient than those conventional algorithms and easily converge.In the end

through two representative examples

synthesis of pattern for square area and China mainland

LCMV proves to be superior to conventional iterative algorithms.
