A 100-Ohm lossless transmission line is to be matched to a load with impedance ZL = 120 - j80 Ohm using a short-circuited stub. Use the Smith chart to determine: (a) the standing wave ratio, (b) the shortest distance from the load to the location of the stub, and (c) the length of the stub in wavelength units. You must clearly show all steps on your Smith chart.
