In which parts of antenna the charges acclerate?

Parts with r-f-current flow, the greatest radiation occurring from
locations along the radiator where current is greatest.

Your words: "Only the change in current and charge, over time, produces
EM
radiation."
At oscillations the current start from zero, accelerate to max speed and
deccelerate to zero.
At the max speed no acceleration at all.

Current flow is near zero at the ends of any unloaded dipole, and at
the top of any unloaded vertical monopole (even those in directional
arrays).

At the ends are the max accelerations and the max radiation.

No, you have it wrong again - the current must be zero at the ends, there is
nowhere for it to go, and there cannot be acceleration of charge is there's
no current. Please go away and read some books and the NEETS module to
which I provided the link.
