Efficient substrate integrated waveguide (SIW) to co-planar waveguide (CPW) transition junction implemented in a multi-layer structure is presented for phased array millimeter-wave applications. The coupling between the two different lines takes place via an aperture (slot) cut on the SIW top ground plane. The transition is simulated by the full-wave solver over the frequency band 29–30 GHz. It shows...
A simple circuit model based on a transmission line (T.L.) model for a dual mode SIW hybrid coupler is presented to calculate the coupler S-parameters. It is simple compared to full-wave solvers, which are time and memory consuming due to huge generated mesh. A case study is presented to validate the proposed model and the simulated results are compared to the full-wave solver results. A very good...
A generic, simple, and fast method using transmission line (T.L.) circuit model that can be used to design and characterize the substrate integrated waveguide (SIW) power splitters, is presented. The T.L. model is based on replacing all the components forming the actual SIW-power splitter structure by their multi-port networks. Two examples, 6 dB and 9 dB SIW-power splitter, are introduced to validate...
