If you think now I am in right direction then you can reply. The impedances and electrical lengths of. I know electrical length (EL) is phase constant (B)* length of the line (l)( this is Physical length as per me, doesn't everybody considers like this, correct me if I am wrong)Ģ.You mentioned physical length = electrical length / sqrt(eps_effective), I am not sure about this, could you tell how this conversion works.ģ.Finally, as I mentioned in the previous post, this is how I convert physical length = EL*lambda/360, which is the point of this thread discussion. Question: Use Smith chart to find the generalized reflection coefficient and the line impedance at discontinuity. At the design frequency, f0, the electrical length of the matching section is. The Smith chart is a graphical tool for determination of the reflection coefficient and impedance along a transmission line. physical length l,, is given in terms of the load reflection.

May be I misunderstood but I want to correct it now.Īnd I also mentioned that 'So I always need to convert from electrical length (EL, found in smith chart utility) to physical length(EL*lambda/360) '.ġ. impedance, zL ZL/Z0, is inside the 1 + jx circle on the Smith chart. As we discussed in class, the Smith Chart represents the complex plane of the reflection.
