Stripline calculation and avoiding Impedance mismatch

Hi Everybody........


I need to design a symmetric stripline with following dimensions.
H= 1.6mm
H/2=H/2=0.8mm
Length = 14.07mm
Width =1.7mm

What kind of PCB can I use to avoid impedance mismatch problem?

At first you have to know what your system impedance Z0 is. Usually it is 50Ohm.
As it looks like you have only one variable, the er of the material.
Probably you could calculate the er with an online strip line calculator like Stripline Impedance Calculator.
However, the er depends of the material and thus it is not available at continuous values. I think it is better to select the material first and then calculate the needed strip with.
