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...

The ontogenetic status of the known specimens alvarezsaurid theropod dinosaurs is revised. We present histological data that holotype Parvicursor remotus from Upper Cretaceous Barungoyot Formation Mongolia not an adult individual, as previously thought, but a juvenile less than one year old. miniaturization took place only in Late Asiatic Parvicursorinae, whereas South American non-parvicursori...
