Composants céramiques 3D innovants pour des applications spatiales de télécommunications millimétriques en bandes Q et V

Abstract : This thesis focus on the development of innovative filtering technologies that enhance the performance to meet the filtering requirements for spacial communications. It is part of the ANR project ATOMIQ coordinated by Thales Alenia Space with partners (SPCTS 3D CERAM). The first chapter consists of a literature review on the Q and V band filters as well as 3D manufacturing technologies. The second chapter is devoted to the development of a new formulation of highly pure, low losses and temperature stable alumina. The third chapter presents a microwave filter design in Q and V band based on a dielectric resonant cavity. The fourth chapter is about the manufacturing of filters and presentation of various demonstrators manufactured by stereolithography and low pressure molding. It also provides a post-production correction solutions based on laser shoots. This work is original because, to the best of our knowledge, 3D ceramic stereolithography and the low pressure molding have not been used to produce small sizes Q and V band microwave filters.
