SUMMARY
The effective dielectric constant for a microstrip on FR4 PCB, with a relative permittivity (er) of 4, can be calculated using the formula e = er * e0, where e0 is the permittivity of free space. This straightforward calculation is essential for accurate RF and microwave circuit design. Understanding this formula allows designers to optimize signal integrity and minimize losses in high-frequency applications.
