A transmission line with a characteristic impedance Zo = 50 Q requires an impedance matching network to match a complex load impedance Z, = 75 – j100 Q at 3 GHz. (You may solve by use of the attached Smith Chart and equations, by equations only or a combination of both.) (a) List and explain three methods of matching the impedance of the load to the feed line. (b) Using the single stub matching network shown in Figure QB1 for which the transmission line of length l and the short-circuited stub of length l2 have 500 characteristic impedances, determine the values of l and l2 in mm assuming that the relative dielectric constant in all transmission lines is ɛ, = 2.1.
