In the framework of the two-dimensional Kondo lattice model with hoppings between first-, second-, and third-nearest neighbors the spin-polaron spectrum is investigated. A complex structure of a spin-polaron and an increase of frustration in spin subsystem leads to the evolution in the excitation ba
