摘要
This paper presents the approach for the design of a X-band bandpass filter using substrate integrated corrugated waveguide (SICW). The SICW filter which is proposed in this paper, is totally realized in a single-layer dielectric substrate with two sequences of metallic vias with the different diameters, and fabricated using a standard PCB process. This proposed filter has the same dispersion characteristics as a waveguide filter, while its dimensions are very shorter than it. A transition circuit between the SICW and 50 Omega microstrip lines was designed for excitation of the filter.
