  High-spin structure of $^{109}$In has been investigated with the
$^{100}$Mo($^{14}$N, 5$n$)$^{109}$In reaction at a beam energy of 78 MeV using
the in-beam $\gamma$ spectroscopic method. The level scheme of $^{109}$In has
been modified considerably and extended by 46 new $\gamma$-rays to the highest
excited state at 8.979 MeV and $J^{\pi}$=(45/2$^{+}$). The new level scheme
consists of eight bands, six of which are identified as dipole bands. The
configurations have been tentatively assigned with the help of the systematics
of neighboring odd-$A$ indium isotopes and the experimental aligned angular
momenta. The dipole bands are then compared with the titled axis cranking
calculation in the framework of covariant density function theory (TAC-CDFT).
The results of theoretical calculation based on the configurations, which
involve one proton hole at the $g_{9/2}$ orbital and two or four unpaired
neutrons at $g_{7/2}$, $d_{5/2}$ and $h_{11/2}$ orbitals, show that the shape
of $^{109}$In undergoes an evolution on both $\beta$ and $\gamma$ deformations
and possible chirality is suggested in $^{109}$In.
