Abstract
We consider an extension of Higgs inflation in which the Higgs field is non-minimally coupled to gravity through its kinetic term. We analyzed power-law coupling functions with positive or negative integer power and found that the Higgs boson can drive a successful inflation only for the cases . Theoretical predictions for both tensor to scalar ratio and scalar spectral index are within the 2018 \textit{Planck} CL. The behavior of the self coupling with respect to the scalar field at the horizon crossing was obtained, and It was found that it can take values in the interval .
