Popis: The high-spin structure of $^{109}$In was investigated with the $^{100}$Mo($^{14}$N, 5$n$)$^{109}$In fusion-evaporation reaction at CIAE, Beijing. Eleven new $\gamma$-rays of $^{109}$In were identified, by which the bandheads of the $\Delta I$=2 rotational bands were confirmed. The configurations were assigned with the help of the systematic discussion. Furthermore, the rotational bands are compared with the tilted-axis cranking calculations based on a relativistic mean-field approach. The rotational bands involving the $1p1h$ excitation to the $\pi$$d_{5/2}$ and $\pi$$g_{7/2}$ orbitals are suggested as candidates for antimagnetic rotation based on the theoretical results.
