A) 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. Afterreplacing 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 0 = 50 0 and the velocity of propagation u =c, determine the following: i) Operating frequency ii) Unknown impedance of microwave antenna. B) It is required to match the antenna in part a to a section of transmission line of characteristic impedance Z. = 50 12. C) It is suggested that we insert a length d of a 50 12 lossless transmission line between the antenna and the side A-A of the double stub tuner. Find the minimum length of such a transmission-line section and the lengths d, and d2 of the stubs required to achieve matching.

Dentify the reasons that support the claim. check all that apply. claim: students should be required to take at least one online class. learning entirely remotely is one option that many schools offer. online classes provide more flexibility in studentsโ schedules. everyone enjoys using a computer, so online learning is more fun than traditional learning. one online class should be a mandated part of any schoolโs curriculum. students learn valuable skills they can apply in online college courses.
