We have proposed a unified CAD-oriented circuit model for accurate representation of radio-frequency (RF), microwave and millimeter-wave planar integrated circuits (ICs) and antennas. This is realized by implementing a so-called “short-open calibration” (SOC) procedure that calibrates (de-embeds) results obtained from full-wave numerical methods such as method of moments (MoM) with two unique calibration standards: short and open elements. This SOC is used to evaluate and to remove unwanted numerical error terms. Following a brief description of our SOC and 3-D MoM in this talk, different classes of planar structures are characterized in terms of their CAD circuit models that involve all physical effects, which are also well verified by our measurements. They are very useful not only in gaining physical insight into the electrical behavior of planar structure but also in implementing efficient network-oriented design/optimization approach. The proposed joint field/circuit models bridge the gap between field simulation/modeling and circuit design/synthesis. New development regarding other numerical calibration schemes will also be discussed in this presentation.
