Find and for the lumped TX circuit shown in Figure 1.3‐right.

Solution: The “incident voltage wave” is the antenna voltage for the ideal match,

(1.19)

The “reflected voltage wave” is simply the actual antenna voltage minus the voltage for the ideal match, that is

(1.20)

Their ratio is given by

(1.21)

which is exactly Eq. (1.17). The reference plane (at either generator or the antenna load) does not matter for the lumped circuit.
