Mechanical design optimization of the radome of an L-band satellite tracking vehicle antenna using R9-strategies and lifecycle assessment

Abstract

This bachelor’s thesis explores the design and material selection of the structure of an L-band satellite tracking vehicle radome, emphasizing on , environmental impact aspect, and lifecycle sustainability.The study compares glass fiber-reinforced polymer (GFRP) with other thermoplastic alternatives: Using mechanical and material property analysis, and the SolidWorks Sustainability module, each material was evaluated for structural durability, electromagnetic compatibility, and environmental sustainability. GFRP demonstrates a superior mechanical strength and electromagnetic transparency, making it a reliable choice for radome applications, However,it has very limited end of life considerations and an altenative thermoplastic that exhibits notable advantages in recyclability, manufacturability, and adaptability to circular economy strategies has been evaluated and selected. This approach demonstrated a scalable methodology for sustainable material selection for incorporating lifecycle thinking at early stage of engineering in satellite communication systems.
