Antipodal two-weight rank metric codes

We consider the class of linear antipodal two-weight rank metric codes and discuss their properties and characterization in terms of t -spreads. It is shown that the dimension of such codes is two and the minimum rank distance is at least half of the length. We construct antipodal two-weight rank metric codes from certain MRD codes. A complete classification of such codes is obtained, when the minimum rank distance is equal to half of the length. As a consequence of our construction of two-weight rank metric codes, we get some explicit two-weight Hamming metric codes.
