Characteristic Impedance Calculation Methods
1. Empirical Formulas:
Empirical formulas provide approximate calculations of characteristic impedance based on simplified assumptions. The most commonly used formula is the microstrip transmission line formula:
Zc = (87 / √εr) * log(5.98h / W + 1.74b / W)
Where:
- Zc = Characteristic impedance
- εr = Relative permittivity (dielectric constant) of the PCB material
- h = Height of the dielectric material (trace thickness)
- W = Width of the trace
- b = Separation between the trace and the reference plane (ground plane)
Note that empirical formulas provide approximate results and may not account for all PCB structure complexities.
2. Field Solver Simulations:
For more accurate results, electromagnetic field solver simulations can be performed using specialized software tools. These consider:
- Specific layer stackup
- Trace geometry
- Dielectric materials
- Other critical factors
Recommended software tools include Ansys HFSS, CST Studio Suite, or Sonnet for high-frequency applications requiring precise impedance control.
