Calculation Formula

W = (Z0 / 60) * (εr + 1.393) - (0.667 * εr - 1.444)

Where:
W = Microstrip Width (mm)
Z0 = Desired Impedance (Ohms)
εr = Dielectric Constant
h = Substrate Height (mm)

How to Use the Calculator

  1. Enter the dielectric constant (εr) of your substrate material.
  2. Enter the height (h) of your substrate in millimeters.
  3. Enter the desired impedance (Z0) of your microstrip line in Ohms.
  4. Click the "Calculate" button to compute the microstrip width.
  5. The calculated width will be displayed in millimeters.

Working Principle

The microstrip width is calculated using the formula:

W = (Z0 / 60) * (εr + 1.393) - (0.667 * εr - 1.444)

Where:

  • W = Microstrip Width (mm)
  • Z0 = Desired Impedance (Ohms)
  • εr = Dielectric Constant
  • h = Substrate Height (mm)

This formula is derived from the transmission line theory and is commonly used in RF and microwave engineering to design microstrip lines.
