Abstract
A new procedure is described for the design of antenna reflector structures for improved performance when subjected to the operational gravity loading. The design objective is to reduce the difference in pathlength of the RF energy beam that is reflected from the deformed surface with respect to the pathlength of the beam from a perfect paraboloidal surface. A virtual work formulation is used to state this objective in terms of the bar areas that compose the structure, which become the design variables. A special application of the Lagrange multiplier technique defines preferential redistributions of the design variables to improve performance. Improvements are developed subject to a primary constraint on total structure weight and additional practical side constraints. Design examples show efficient and effective applications of the described procedure.
