A circuit model is presented for the modeling of mutual coupling for substrate integrated waveguide (SIW)-series fed dielectric resonator antenna (DRA) array excited by longitudinal slots. The antenna element can be modeled using S-parameters or π equivalent circuit. The mutual coupling between antennas is modeled as a two-port network shunt connected between adjacent antennas. A four elements millimeter-wave...
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 hybrid numerical simulation method is presented to model and analyze integrated terahertz (THz) photomixer antennas. The proposed computational method combines an optoelectronic solver and a full-wave electromagnetic solver to rigorously model continuous wave (CW) THz photomixer sources. In this hybrid computational approach, the photomixer source is modeled in a rigorous manner without any approximation...
