Is the pulsative flow of electrons in antennas?

no, the flow of electrons stays in the antenna and is sinusoidal...

In a cristal radio is the diode. The electrons flow from the antenna to
ground. Where they come from?

they do not jump off the antenna.

They must do it in the transmitting antenna.
They are members of "pulsatile- composed of a mean
flow superposed with an oscillating component".

In reality no "sinusoidal...". The forward motion is always stronger than
the back.
