Etude et conception de filtres hyperfréquences hybrides planaires-volumiques

Abstract : Modern systems of telecommunication touch an increasingly large audience, this induces unrelentingly an intense use of the microwave spectrum. To avoid saturation of the available services, specifications on the systems are increasingly demanding and these drastic constraints are deferred on the various elements and in particular on filters. In this PhD dissertation, we present a new technology of filters, the objective is here to improve the electric performances of the filters without giving up the ease of realization of these circuits. Thus, in the first chapter, we introduce the two historical technologies of filters, planar and waveguide ones. A new technique combining advantages of these two technologies is then presented. This one is called Substrate Integrated Waveguide (SIW) and consists in delimitating cavities into the planar substrate. In the second chapter, we propose improvements concerning this SIW technique, improvements are related not only to topologies of the resonators but also to couplings between resonators. In the last chapter, we present a new topology of filter based on a recombination between planar elements and integrated cavities. We also present the synthesis of this topology. Main advantages of this topology are an easy design as well as good electric performances.
