  Theoretical calculations are performed to understand the electronic structure
and magnetic properties of CuFe$_2$Ge$_2$. The band structure reveal large
electron density $N(E_F)$ at the Fermi level suggesting strong itinerant
character of magnetism. The Fermi surface is dominated by two dimensional sheet
like structures, with potentially strong nesting between them. The magnetic
ground state appears to be ferromagnetic along $a$ and antiferromagnetic in
other directions. The results show that CuFe$_2$Ge$_2$ is an antiferromagnetic
metal, with similarities to the Fe-based superconductors; such as magnetism
with substantial itinerant character and coupling between magnetic order and
electrons at the Fermi energy.
