01 / 07Microstrip impedance
Uncovered surface trace · quasi-static estimate
Results will appear here.
Model limits. Zero-thickness copper model. No mask, roughness, dispersion or connector effects. Frequency sets wavelength only; impedance is quasi-static. Final geometry needs field-solver and fabricator verification. Read the methodology.
Use the result in a real design
01 · Set the construction
Use the approved dielectric spacing and material model. Keep units explicit.
02 · Check the assumptions
Compare the model limits with the geometry and frequency of your circuit.
03 · Prepare the release
Export the brief, then obtain field-solver and fabrication review.
