Deux filtres passe-bande (BPF) à double bande basés sur les structures de résonateurs à impédance étagée (SIR) doublement couplés en parallèle ont été proposés dans cet article. Les SIR couplés avec/sans charges à tronçon ouvert sont introduits dans la conception du filtre. Les filtres double bande présentant plusieurs zéros fonctionnent à 2.45/5.2 GHz pour les applications WLAN. Deux filtres à trois étages composés de quatre SIR ont été proposés avec la ligne de prises adaptée dans les sections d'E/S. Un filtre à cinq étages est construit sur la base du même principe de conception pour obtenir une meilleure réjection de bande. Les filtres proposés présentent les avantages d'une bande passante beaucoup plus large dans les deux bandes passantes sans sacrifier la perte d'insertion et la planéité de la bande passante. La procédure de conception d'un modèle classique de lignes microruban couplées en parallèle est toujours adaptée à la conception des filtres proposés. Les filtres proposés ont atteint près de deux fois la bande passante d'une configuration conventionnelle de lignes couplées en parallèle avec les mêmes paramètres de conception. Les expériences ont été menées pour vérifier les performances du filtre. Les résultats mesurés sont en bon accord avec les résultats de simulation pleine onde.

Abstract: Two dual-band bandpass filters (BPFs) based on the doubly parallel-coupled stepped impedance resonators (SIRs) structures have been proposed in this paper. The coupled-SIRs with/without open-stub-loads are introduced in the filter design. The dual-band filters exhibiting multiple zeros design operate at 2.45/5.2-GHz for the WLAN applications. Two three-staged filters composed of four SIRs have been proposed with the tapped-line adapted in the I/O sections. A five-staged filter is constructed based on the same design principle to achieve a better band-rejection. The proposed filters have the advantages of a much wider bandwidth in both the passbands without sacrificing the passband's insertion loss and passband flatness. The design procedure for a conventional parallel-coupled microstrip lines model is still suitable to design the proposed filters. The proposed filters have achieved almost twice the bandwidth of a conventional parallel-coupled lines configuration under the same design parameters. The experiments have been conducted to verify filter performance. Measured results are in good agreement with the full-wave simulation results.
