Embedded Microstrip Impedance Calculator

An embedded microstrip is a microstrip transmission line or flat conductor separated from the ground place via a dielectric material. There is also a dielectric material placed above the conductor.

Calculate the Impedance of an Embedded Microstrip Transmission Line

Note: This Calculator works for W/H < 1

  • Trace Width (w)
    mils
  • Trace Thickness (t)
    mils
  • Trace Dielectric Thickness (h)
    mils
  • Overall Dielectric Thickness (h1)
    mils
  • Dielectric Constant (εr)
  • Calculate Reset

Result

  • Impedance (Z0)
    Ω
  • Propagation Delay (Tpd)

Where,

Z= Impedance

Tpd = Propagation Dealy

w = Trace Width

t = Trace Thickness

h = Trace Dielectric Thickness

h1 = Overall Dielectric Thickness

ε= Relative Dielectric Constant

 

Example,

If w = 7 mils, t = 1.2 mils, h = 4 mils, h1 = 6.4 mils and εr= 4 then,

Z0 = 39.4277 Ω and Tpd =135.18 ps/inch
