The first case investigated had the following parameters: The parameters given above should correspond to a microstrip line with characteristic impedance, Z 0 of 50 Ω. Figure 2 shows the relationship ...
All 50Ω microstrip lines in FR4 have the same aspect ratio. Using a 2D field solver, we can explore what this ratio is for a specific value of Dk (dielectric constant) and conductor thickness. Spoiler ...
