Question

A 50-Ω air transmission line terminated with an unknown load ZL is excited by a 6 GHz sinusoidal signal source. The standing wave ratio on the line is measured to be 4 and the position of one of the voltage minimums on the line with respect to the load position is 9 cm. Determine the value of the load impedance ZL and box your answer.
