Abstract In this paper, a new design approach for the six-port (SP) junction is introduced. The proposed includes generalized broadband matching and smooth miniaturization scheme extendable any passive multiport structure. A multilayer technology microstrip to slot coupling operation are employed designed SP, which comprises power divider three hybrid couplers. conducted measurements of constru...

Abstract This contribution presents miniaturization techniques for folded circular substrate integrated waveguide (FCSIW) cavity filters. The cavities support dual-mode operation. Two of these are combined to form a fourth-order filter. filter designs implemented. first one serves as reference and exhibits good manufacturability. For the second one, is modified, which leads $50\%$ more compactn...

While the application of optical and photonic technologies in the communications, computing, medicine and industrial manufacturing has been growing rapidly, the miniaturization of these technologies has been slow due to the limitation on the diffraction. However, the developments of nanoscale components and guiding methods are continuing with a rapid pace. Since waveguiding is a fundamental iss...
