5. a. A transmission line has characteristic impedance of 75 and it is connected to receiver with Z. = 100 150 , using smith chart to find: (4 Marks) (4 Marks) i. Reflection Coefficient; ii. VSWR b. A 45.6 m long transmission line with a characteristic impedance of 100ohms is terminated with an antenna of unknown impedance. There is mismatch in the system and the standing waves have a Vmax =6 V and V min=1.5 V. The distance between two successive minima is 6 m. Distance of the first voltage minima from the load end is at 2.4 m. Using a Smith Chart calculate the following: i. Calculate the reflection coefficient; ii. Calculate the input impedance of the line; ii. Design a short circuited stub to match the antenna to the line
