The self-consistent electronic structure of antiferromagnetic NdB{sub 6} is investigated for the purpose of deriving systematic properties in rare-earth hexaboride systems. Employing the linearized muffin-tin-orbital band method within the local-density approximation, band structures and Fermi surfaces of both paramagnetic and antiferromagnetic phases of NdB{sub 6} are determined. Results are compared with those of non-{ital f}-electron system, LaB{sub 6}, and also with de Haas--van Alphen experiments. Overall electronic properties of paramagnetic NdB{sub 6} are similar to the ones of LaB{sub 6}. The band structure and Fermi surface in the antiferromagnetic phase of NdB{sub 6} are accounted for rather well by a folding mechanism of paramagnetic counterparts.
