But what radiate in 0.05WL dipole? There the

The feed point is also in the transmissing line.

Pick one of the above comments, only, Szczepan.

The feed points are terminals of the antenna. On center-fed dipoles
that are 1/2WL or less in length, antenna current is highest at those
terminals.

How long are the folded dipoles and the
loop antennas? Are there the short version?

They can be any length, but some lengths have better input
characteristics and/or more useful radiation patterns than others.
