Abstract
Optimality criteria design is applied for large antenna structures with multiple constraints on microwave performance. The constraints are on accuracy of the structure: restrictions on the microwave pathlength error, and the antenna pointing error. The examples given show convergence to low-weight feasible designs that satisfy the constraints. Truss-member sizes are automatically selected from tables of commerciaily available structural shapes, and approximations resulting from the method of selection are found moderate. The multiple constraint design is shown to be more effective in meeting constraints than the old envelope method. For practical structures, the new design method can be performed within reasonable core size and computation time.
