High spin states of ${}^{112}$In were investigated using the reaction ${}^{110}$Pd(${}^7$Li,5$n$)${}^{112}$In at a beam energy of 50 MeV. A new level sequence has been found in this nucleus and the configuration $\pi g_{9/2}^{-2}{g}_{7/2}\otimes \nu h_{11/2}$ before the alignment and the configuation $\pi g_{9/2}^{-2}{g}_{7/2}\otimes \nu h_{11/2}^3$ after the alignment are assigned. The self-consistent titled axis cranking relativistic mean-field model calculations are performed to interpret the rotational structure and the characteristic features of antimagnetic rotation have been presented for the band after backbend.
