A multichannel phase-shift analysis has been performed for the first time on the available experimental data of all the channels of $\overline{K}N$ interactions in the momentum region 0 to 1200 MeV/c. The Argand diagrams of the reaction amplitudes and the resonance parameters within the momentum region are given. The results provide stronger evidence for a number of previously suggested resonances and also indicate some new possible resonances.
