Étude de filtres hyperfréquence SIW et hybride-planaire SIW en technologie LTCC

Abstract : Control of communication and information is a key asset in the strategies of power, whether military, political or commercial. Whoever is able to transmit information faster takes advantage of others. This is the engine of growth and progress in the field of telecommunications. The growing ubiquity of communicating devices demonstrates the exponential growth experienced by this area since the first wireless communications. At the time of all-in-one, multiple applications within a single device requires the use of ever more powerful and small components. At the heart of these systems, filters are becoming increasingly important. In a space environment, reliability constraints and space are particularly dramatic. The choice of materials is also limited, which reduces the possibilities of innovation. However, the improvement of accuracy and reliability in manufacturing technologies opens new opportunities for innovation and improved components. This work has been motivated by the desire to bring more performances and reliability, a smaller footprint by taking advantage of the potential offered by combining the concept SIW and LTCC. The results update serious technological dispersions. However, the potential association SIW / LTCC is shown, and the difficulties are surmountable. SIW filters in LTCC therefore have advantages for itself as a serious alternative to existing solutions.
