For series stub matching, the parameter used for matching is:
For series stub matching, the parameter used for matching is: Correct Answer Impedance of the transmission line at a point
In series sub matching, the distance‘d’ is selected so that the impedance, Z seen looking into the line at a distance‘d’ from the load is of the form Zₒ+jX. Then the stub reactance is chosen as –jX resulting in a matched condition.
