the assignment , i need answer

Apply the input impedance formula for a ?2 and ?4 transmission lines. Compare and comment on any of the two cases which provide impedance transformation exploited in impedance matching techniques. (25 Marks) 2. An Ethernet cable is used to connect a computer to a server and it is found experimentally that ??.? ?? 120 Ω ??? ??.? ?? 500 Ω. The cable is terminated with a sever having a load resistance ?? of 500Ω at frequency of 300MHz. Design a single stub matching to minimize the reflection on this cable without using the Smith Chart. (15 Marks) 3 a) A lossless transmission line of length ?=0.4λ is terminated with a complex load impedance ZL=60 j50 Ω and characteristic impedance (Z0=50 Ω). Use Smith Chart to find: i. The VSWR on the line; (2 Marks) ii. The reflection coefficient at the load and its phase angle; (2 Marks) iii. The load admittance of the line ?? in S; (2 Marks) iv. The input impedance of the line in Ω; (3 Marks) v. The distance to the first voltage minimum from the load in λ; and (3 Marks) vi. The distance to the first voltage maximum from the load in λ. (3 Marks) b) By calculation only, verify the following parameters in Q3 part(a): i. The input impedance of the line in Ω. (5 Marks) ii. The distance to the first voltage minimum from the load in λ. (5 Marks) iii. The distance to the first voltage maximum from the load in λ. (5 Marks) 4 Load impedance ??=30−?40 Ω is to be matched with a 50 Ω line. Use Smith Chart to find solutions using the following types of single series tuning stubs i. Open-circuited stub tuner. (10 Marks) ii. Short-circuited stub tuner. (10 Marks) 5. a) At very large frequency (VLF) ranges, it is practically not possible to transmit horizontally polarized waves. Give reasons. (5 Marks) b) Give the significance of radiation resistance of an antenna. Calculate the radiation resistance of a ?/10 wire dipole antenna in free space.
