How to Use the Asymmetric Stripline Impedance Calculator

Here’s how you can compute the characteristic impedance:

1. Enter Dielectric Constants (εr): Specify the relative permittivity of the materials above and below the signal trace.
2. Input Trace Width (W): Provide the width of the signal trace in millimeters or inches.
3. Enter Layer Spacing (H1 and H2): Input the thickness of the dielectric layers above and below the trace.
4. Specify Trace Thickness (T): Define the thickness of the conductive trace.
5. Click Calculate: The tool will instantly compute the characteristic impedance based on the input values.

Formula

The characteristic impedance Z0Z_0Z0​ for an asymmetric stripline is computed using advanced electromagnetic field equations, typically simplified as: Z0=f (ϵr, W, T, H1, H2) Where:

• ϵr​: Relative permittivity of the dielectric material.
• W: Trace width.
• T: Trace thickness.
• $H1$ and $H2$: Dielectric thickness above and below the trace, respectively.

This calculator integrates these parameters to provide precise impedance values tailored to your design.
