A coupled microstrip line is to be designed for a substrate having a thickness of 2.0 mm and dielectric constant of 10.0. The required even- and odd-mode characteristic impedances are 133 Ω and 71.5 Ω, respectively. Use the graph of Figure 7.30 to find the required line widths and separation. If possible, compare your results to those obtained from a microwave CAD tool.
