“…Multi-mode SIW resonators have been presented in [10]- [15] for the realization of compact-size single/multi-band BPFs. In particular, in [10], [11], [14], and [15], cavity resonators with two capacitively-loaded posts are reported to either increase the number of poles per resonator in the static BPF in [10], [14], and [15] or to create independently-controlled dual-passband filtering responses in terms of center frequency in [11]. In yet another configuration [12], dual-band BPFs are created by splitting the capacitive post of a coaxial cavity in four highly-coupled parts.…”

This paper reports on dual-mode-cavity-resonator-based bandpass filters (BPFs) with multiple levels of transfer-function tunability. They are based on substrate-integrated-waveguide cavity resonators that are loaded by four identical metallic posts and give rise to two degenerate modes that are exploited for the filter design. By loading the ends of the posts with variable-reactance elements, quasi-elliptic-type filtering transfer functions with multiple levels of spectral adaptivity can be obtained. These reconfiguration properties include center-frequency control, bandwidth tuning, and intrinsic RF switching-off. The proposed adaptive BPF concept can be extended to high-order transfer functions shaped by 2N poles and 2N transmission zeros (TZs) for BPFs composed of N dual-mode resonators. To prove the experimental viability of the engineered tunable BPF concept, a two-pole/two-TZ prototype and a four-pole/four-TZ prototype with tunable transfer functions in the 1.5-3 GHz band were built and measured. INDEX TERMS Bandpass filter, bandwidth tuning, cavity filter, dual-mode filter, tunable filter, reconfigurable filter, RF filter, substrate-integrated-waveguide (SIW) filter.

“…Recently, however, the evolution of telecommunication satellite payloads is requiring the development of new filter structures that could allow for the remote variation of both filter center frequency and bandwidth [36]. In response to this new requirement, initial investigations have appeared in the technical literature discussing new, tunable dual-mode filter structures (see for instance [20], [37], and [38]). Furthermore, a very recent contribution [39], described the initial results of an investigation aimed at exploring the maximum tuning range for the class of filters based on the structure shown in Fig.…”

The objective of this paper is to use Electromagnetic based Computer-Aided Design tools to investigate the maximum tuning range of channel filters, typically used in satellite payloads. Both circular and rectangular waveguide technologies are investigated. The results of the investigation show that single-mode rectangular waveguide implementations offer substantially wider tuning range, as opposed to classical dual-mode circular waveguide implementations. In addition to simulations, measurements are also presented indicating very good agreement with theory, thereby fully validating the Computer-Aided Design procedure.

La present tesis doctoral té com a objectiu el estudi, desenvolupament, diseny i fabricació de nous components pasius de microones, tals com els ltres i multiplexors que operen en les bandes d'alta freqüencia dels actuals i futurs satèl•lits de telecomunicació (bandes Ku, K i Ka) entre 12 i 40 GHz, Aquests components han de ser capaços d'oferir tant, respostes clàsiques sencilles com avançades (eliptiques), i que a més a més presenten una capacitat de resintonització (tant en termes de freqüència central com d'amplada de banda). Aquestos nous components pasius donaràn solució a les necesitats dels actuals sistemes espacials, que requereixen de majors taxes de transmissió de dades (senyals de major amplada de banda), així com de major exibilitat en les frequencies de operació, per oferir en un mateix dispositiu distints serveis i prestacions.Per aquesta raó, es proposen tant modicacions a les estructures del ltres clàsics de microones actuals, com la introducció de noves estructures.Així mateix, també s'investigarà l'us dels tornells d'ajustament post-fabricació dels ltres com a tornells de sintonía metàl•lica i la introducció de tornells de sintonía realitzats amb diferents materials dielèctrics Es pretén, d'aquesta forma, la millora de les respostes del dispositius actuals; reduint la envergadura i els costos de producció (gràcies a la relaxació de les toleràncies de fabricació), abaratint d'aquesta forma la fabricació i futura operació dels ltres mateixos.Aprotant aquestos nous dispositius es treballarà també en el disseny, fabricaçió i mesura de components més complexes, com poden ser els multiplexors de canal i els commutadors amb resposta selectiva en freqüencia, tots ells necessaris en els sistemes de comunicacions espacials i en íntima relació amb els ltres abans esmenats.Per nalitzar, el desenvolupament de tots aquestos dispositius vindrà acompanyat d'una metodologia de disseny basada en l'us del Mapatge Espacial Agressiu (Aggressive Space Mapping, ASM), especialment adaptat als ltres en guia d'ona.vii
