Please, I want the solution in two ways:
Method 1 (without the Smith chart):
Method 2 (using the Smith chart):
A short circuit stub of length 0.04λ is used to match a 50 Ω lossless line to a load ZL = RL + j30 Ω. Use Smith chart to find:(a) The distance between the stub and the load.(b) The value of RL .
