The Characteristic Impedance of a Stripline Calculator is a tool that computes the characteristic impedance of a stripline based on specific parameters related to the substrate material and trace dimensions. Understanding the characteristic impedance is crucial in designing high-frequency circuits and transmission lines.
Formula of Characteristic Impedance of a Stripline Calculator
The formula used for calculating the characteristic impedance (Z₀) of a stripline is:
Z₀ = (87 / sqrt(εr + 1.41)) * ln(5.98 * h / w + 1.41)
- Z₀ is the characteristic impedance in ohms.
- εr represents the relative permittivity (dielectric constant) of the substrate material.
- h denotes the height of the substrate in inches or meters.
- w signifies the width of the trace in inches or meters.
