Substrate integrated waveguide H-plane filter

Novel double layer Substrate Integrated Waveguide (SIW) technology is used for realization of conventional H-Plane filter which is manufactured in waveguide. This proposed filter is totally realized in double layer dielectric substrate with metallic vias and fabricated using a standard printed circuit board(PCB) process. In previous works, prototypes of E _Plane and H-Plane filter were designed and fabricated in standard waveguides. The H-Plane type of those has the same frequency response as that of E-Plane type while its cross section is one-quarter. Similarly, the SIW H-Plane filter, which is presented in this paper, has the same dispersion characteristics as that of waveguide filter while its dimensions is very shorter. Moreover, by using a sandwich model of double layer SIW, the interleaved metal vane is fabricated between two substrate easily.
