Constant circles and electrical-length radials. For example, the normalized impedance for a load Z L 73 + j42 on a 50 transmission line is Z LN 1.46 + j0.84 By plotting the normalized load impedance on a Smith Chart, the input. If you think now I am in right direction then you can reply. This paper presents Smith Chart as a graph based method of simplifying the complex math needed to. The Smith Chart works with normalized impedance and admittance, where normalization is made with respect to the characteristicimpedance of the transmission line.

Figure 1: A variety of lumped-element impedance matching circuits for impedance.

In the next paragraph, we will use the orange path on the Smith Chart, with intermediate impedance. 28K views 2 years ago UNITED STATES In this video, i have explained Smith Chart Example for Series Stub Matching using standing pattern with following outlines. 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. Input Reflection Coefficient and Impedance on Smith Chart. 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. Suppose we have a transmission line with a characteristic impedance of 50 ohms, and an electrical length of 0.3.
