The illustration shows a circuit where a feedline connects a generator with load, Y sub L equals (0.4 plus j 0.8) Y sub 0. A 50 n H inductor is connected in parallel on the feedline at a distance of d sub 1 equals 0.063 lambda, with input impedance labeled Y sub d1.

The Smith chart shows families of r sub L and x sub L circles. Point A representing load z sub L and point B representing load y sub L are located on the S W R circle, in the lower and upper parts of the chart, respectively. Point C is located at the first intersection of S W R circle with g sub L equals 1 circle, with C representing y sub d sub 1 equals 1 plus j 1.58. The distance of B to C is d sub 1 equals 0.063 lambda.
