WebbThe admittance form of the Smith chart is used in the following example. Example 14.6.1. Single Stub Matching. In Fig. 14.6.6a, the load admittance Y L is to be matched to a transmission line having characteristic admittance Y o by means of a "stub" consisting of a shorted section of line having the same characteristic admittance Y o.Variables that can … WebbWe'll now look at standing waves on the transmission line. Assuming the propagation constant is purely imaginary (lossless line), We can re-write the voltage and current waves as: If we plot the voltage along the transmission line, we observe a series of peaks and minimums, which repeat a full cycle every half-wavelength. linktown bsd city
