The properties of the half-filled Kondo lattice model with anisotropic intersubsystem exchange interaction JXY and JZ are discussed. The phase diagram and ground state characteristics of the system are determined within a variational mean-field approximation for the case of rectangular density of states (DOS) for itinerant electrons. The ground state phase diagram is found to exhibit five different phases: Kondo singlet state, two planar antiferromagnetic phases, and two Ising antiferromagnetic (Néel) phases.
