Abstract
This research is aimed at exploring the potential for reducing the overall mass of large space structures on which space systems are supported. A key component of these systems comprises microwave arrayed antennas, which are distributed across the surface of the structure. Given that dielectric materials constitute a significant portion of the antenna mass, this study is primarily concerned with minimizing the mass of these antenna dielectrics. It is crucial to note that while reducing mass is a priority, the stiffness of the antenna system must be preserved, as it needs to adhere securely to the structure’s surface. To achieve this objective, we embark on a process of optimizing the topological distribution of the dielectric material. We investigate how this optimized configuration impacts the microwave characteristics of a patch antenna. Our approach involves conducting topological optimization while concurrently ensuring structural stiffness. Subsequently, we assess the influence of this optimized distribution on the antenna’s patterns and gains using different materials.
