  We study the anomalous Hall effect and orbital magnetization in chiral
antiferromagnets, constructing a simple tight-binding model on a stacked Kagome
lattice structure with spin-orbit coupling and the exchange interaction between
the localized spins and itinerant electrons. It is shown that the ground state
is an orbital ferromagnet with the easy-plane anisotropy. The relation between
the orbital magnetization and the configuration of the Weyl points are
discussed.
