This chapter reviews various numerical methods applied broadly in space antenna simulations, in which three popular full‐wave simulation methods are specifically depicted. First, the basic theory of such methods and their applications in antenna simulations are briefly given. Then the related fast algorithms are discussed. Method of moments (MOM) can deal with open problems naturally and needs only surface discretization. Finite element method (FEM) is a versatile technique in dealing with complex structures and inhomogeneous materials. The finite difference time‐domain (FDTD) method has good computational complexity, being matrix free, and can give abundant time information on the physical model. For some complex cases, the adoption of one single method is inefficient, or even impossible to solve some problems. In such circumstances, hybrid methods are preferred, such as a combination of MOM or FEM with high‐frequency methods.
