[LEFT]Hello engineers, I got the right answer from my professor here in the United States...
The main difference between the standing-wave current antenna and the traveling wave current antenna is the reflection. So, in the standing-wave current antenna, all of the forward energy is
reflected at the open end of the wire. The total current is the sum of the forward and reflected currents which are close to equal.
While in the traveling-wave current, most of the forward energy
is dissipated in the load resistor rather than being reflected. The total current is the sum of the forward and reflected currents with the reflected current minimized to a negligible value.
