I have read in some papers that the printed dipole structures have a higher cross-polarization level.
But I couldn't found a reason or proof for why this configuration produces very high cross-polarization.
Can anyone explain it to me Or introduce a reference?

Thanks in advance

First of all the antenna you posted is not a dipole. A dipole should have two arms and a differential feed:

Usually the high cross polarization in printed dipoles is produced by the printed balun, and not by the dipole itself.
For example a wire dipole antenna placed in the air do not use a printed balun.
Minimizing the dimensions of the printed balun or integrating somehow in the dipole arms, will improve the cross polarization performances.
