What is the aspect ratio for 50Ω microstrip?: Rule of Thumb #27

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 ...

What is the aspect ratio for 50Ω stripline?: Rule of Thumb #28

All 50Ω symmetric striplines 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 and conductor thickness. Spoiler summary: The ...
