  We consider a bottom-up AdS/QCD model with a conformal exponential
deformation $e^{k\,z^2}$ on a Lorentz invariant AdS background. In this model,
we assume the conformal dimension associated with the operator that creates
pions at the boundary as $\Delta=3$. Regarding the infrared scale related to
photon field $k_\gamma$, we analyze two cases: constant and depending on the
transferred momentum $q$. In these two cases, we computed the electromagnetic
pion form factor as well as the pion radius. We compare our results with
experimental data as well as other theoretical (holographic and
non-holographic) models. In particular, for the momentum-dependent infrared
scale, we find good agreement with the available experimental data as well as
non-holographic models.
