We analyse the conductance of the Aharonov-Bohm one-dimensional quantum ring
touching a quantum wire. It is shown that in accordance with experimental data
the period of the AB oscillations strongly depends on the chemical potential
and the Rashba coupling parameter. The dependence of the conductance on the
carrier's energy is shown to reveal the Fano resonances.
