In an experiment to determine the unknown impedance of a microwave antenna, a slotted section of transmission line is first connected to a short-circuit load. In this case, adjacent voltage minima are found 23.6 and 35.4 cm away from the load. After replacing the short circuit with the antenna, the location of minima shifted to points 27.8 and 39.6 cm respectively, away from the load with the VSWR value equal to 2.6. Assuming that the slotted transmission line is lossless of characteristic impedance Z. = 50 1 and the velocity of propagation u = c, determine the following: (i) Operating frequency (ii) Unknown impedance of microwave antenna.
