Etude de filtres hyperfréquences compacts à basse fréquence

Abstract : Recent developments in microwave systems lead to drastic constraints on the size and cost of components, and in particularly on Passband Filters (BPF). The aim of this thesis was to provide innovative solutions for low band compact broadband filtering. We proposed two topological solutions of compactness.The first solution focuses on improving the compactness of the resonator thanks to the multisections resonator. This topology has been theorized and modeled to optimize it. The compactness provided by the multi-sections resonator has been shown by the realization of interdigital filters. The second solution is a new topology of the combline filter, electrical coupling combline filter (ECC).We have also shown that these topological solutions are compatible with other technological solutions of compactness (multilayer ...).These solutions solve the size and integration problems of current filters with equivalentelectrical performance.
